Tinta — the mount, in real life and in FreeCAD

Wowzers. I completed the list!
That's about a first.
And whilst it was a short list, some of those items weren't exactly trivial.
- Car refuelled & shopping done ✅
- French pattress box extender (redesigned in #FreeCAD and printed) ✅
- Suffolk printed (after a lot of svg/cad fettling!) ✅ (No Nofolk alas)
- Joule Thief Cat soldered, with added backup USB power injection for when I don't have "dead" batteries for it ✅ (needs cleaning up, but works! I broke my flush cutters a while back, so have ordered a nice fancy Knippex pair to arrive tomorrow.)
And made a (fairly basic) BBQ dinner of Barnsley chops, garlic/chilli potatoes & broccoli, and BBQed eggplant.
Bonus: got a hair cut by an actual hair cutting person for the first time in well over a decade. (My usual thing is I just shave it off every 2-3 months.)

You'd think #FreeCAD would have a simple and intuitive way to "copy" a sketch, aka "duplicate" - but buggered if I can find it, and DDG/Google searching isn't helping much. (I am very very impatient with software these days lol.)

Of course, at some point in the 2000s a designer at #renault decided that a flat roof rack is practical but not looking nice. So they curved it by 15mm (7.5mm on each side).
My "new" 1983 vintage roof box is not curved on the bottom side. It got steel tubing and a sturdy zigzag pattern on the bottom. It. Will. Not. Bend. And that's fine.
So to mount it in 2026 I need spacers. And as we live in the future™ now I just fired up #freecad and let the #3dprinter do the work.
This is no shiny fancy thing, just a wedge with a hole. But in 2026 it just makes sense to let the machines do the job - I would not be faster/better if I started to cut and grind plastic or wood.
Tested at up to 130 km/h the roof box is nice: nearly no sound, just a silent "sssshhh" wind noise, and its not noticeable regarding driving dynamics at least in empty state. and the whole thing is just 2m tall.

Hey wonderful people, it's #FreeCADFriday once again! What are you working on in #FreeCAD at the moment?!

One further design iteration of my 3D printed lens hood/light baffle seems to have done the trick. v5b goes back to the 5 mm long, 2 perimeters thick telescope interface but bumps up the diameter just slightly for a snug push fit into the aperture on the 'scope. The thread is in place to stop it dropping on to the concrete patio tiles when the Seestar closes itself at the end of the night so hopefully I won't get any more broken lens hoods.
I've designed all these so that they shouldn't induce any vignetting at all, but I'll still take some new twilight flats shortly just in case the illumination is slightly different to the previous version.
The weather forecast says it'll be clear pretty much all night but that humidity will hit 99% by around midnight so it'll probably be foggy before morning. Definitely a night to turn the dew heater on, but the lens hood should also help keep condensation off the lens.

I was asked to help with a new fiber connection, so I assisted with some planning and provided these 3D-printed conduit seals:
They are made up of two symmetric halves that fit together without slipping. Clamp them around the cable and push them into the tube. Simple.
As always, I provide the @freecad file along with the printable files so you can inspect and adapt the model.

Test ride with temporarily mounted speaker (at the air intake) was more or less a success. Instead of single bell ringing sounds I mixed some together into a longer sequence for upcoming tests.

Rapid prototyping.
I quickly knocked up v5a of my lens hood/light baffle design (loop for attaching a thread, telescope interface wall 3 perimeters thick instead of 2, but 3 mm long instead of 5, opening half angle increased from 2.3° to 2.4°), printed it on my Prusa Mini+, and put it on the telescope by the time the night was about half over.
I'm pretty happy with the design but it did expose the issues with relying on a push fit. Despite being designed with the exact same outer diameter as my previous lens hoods this one (and only this one) was too loose, and was going to fall out when the telescope moved. An emergency application of a single strip of masking tape on the interface surface to tighten it up may just be enough to keep it in place for tonight, but I'll need to investigate more tomorrow.
I may be partly due to my printer producing a smoother surface than the previous prints that suffered from cold conditions, but I suspect it was actually the shortening by 2 mm that is the main problem. Now that I think about it I recall there being a fine moulding line or seam between parts a few mm inside the aperture. My previous lens hood might have been relying on that for grip, and the new one doesn't quite reach it. I can tweak the dimensions to try to get the perfect fit but I really should find a way to use the magnets instead.

Warum nicht gleich so, und out of the Box? Nach mehrstündigem, hartem Kampf endlich die #SpaceMouse von #3dconnexion unter #FreeCAD 1.1.1 zum Laufen bewegt. Neue Version aus den Quellen kompiliert, den #AppImageLauncher ebenfalls und die Benutzergruppe des konstruierenden Users angepasst.
Benutzerfreundlich ist was anderes.

Another video promoting #FreeCad. In this video this guy shows you how to model a bike frame in FreeCAD, covering all the techniques that professional designers use to create this model.
Educational and clear how complex designs can be created with open-source tools!

For over five years the battery charger for our electric bicycle has been awkwardly dangling from a little hook.
With emotional support from toddler and actual support from #FreeCAD I finally created a simple wall bracket.
It's available from .stl sharing site #manifold :-)
Inner dimensions are 73mm by 42,5mm. With a hole in the bottom for a cable exit. Probably fits other chargers as well.

#weeklyreview 02/2026
Summary
week 02 of 2026 was still somewhat relaxing as I was still on vacation formally. Took the time to work on our house project25
- Sunday: back to Berlin, watching Lord of the Rings Extended Edition with the kids again. Still epic
- Monday: more learning and tinkering with FreeCAD for projeckt25, attempted shoe shopping with kiddo at Alexa
- Tuesday: more FreeCAD tinkering, 3D Printer Nozzle swap to an 0.2mm nozzle, bringing a friend over to the Fediverse
- Wednesday: onsite project25 for detailed measurement
- Thursday: office stuff and walk in the park, anticipating severe weather on Friday
- Friday: project25 deconstruction, no severe weather in and around Berlin at all
- Saturday: project25 deconstruction, dinner with a friend who brought craft chocolate from Switzerland.
Project25 works
This week the first craftsmen started their work. First things are the roof windows and reinforcment of the roof for the insulation.
Our roof tiler/carpenter is a really nice guy I know from my time at school in the town. Of course it turned out I ordered some windows in the wrong colour. Wood instead of plastic white. Fortunately we hadn’t opened the boxes yet. So I called the webshop I had ordered the windows from and they happily offered to swap the wrong windows out for just the price difference. That was easier than I thought.
Also ordered another small window to replace the small window meant for the chimneysweeper to get out on the roof.
The new windows will bring much more light into the attic.
On Wednesday I was on site to take precise measures of all the rooms and feature with my new laser distance meater. Much easier than crawling around with these foldable measure sticks. Plan is to build a digital twin with FreeCAD in which I can to the further planning.
On Friday and Saturday I’ve got help from my brother to rip out some old drywalling and bricks in the attic that need to go out before the insulation and builtout starts in the attic. The 30 year old styrofoam was ultra brittle and dissolved to dust when we tried to touch it. Eventually we used a vacuum to get it all off. Some animals had build themselves a nest in the insulation rock whool and hauled a whole bunch of walnuts in there.
3D Printing
A friend asked me to produce some dust caps for USB-A and USB-C ports. Of course there are readimade models on Printables & Co.
I tried with my default 0.4mm Nozzle first but wasn’t happy with the result. The small structures seem a bit too rough for my taste. I decided to swap out the nozzle for a smaller 0.2mm diameter one. Did some calibrations and now the objects came out much smoother and with higher precision.
Only drawback is of course the longer print time.
Fediverse
A friend started using his Mastodon account. He had created it initially a while ago, but stared to actually use it last week. We were talking every once in a while about it and I tried to get him over. But so far he hadn’t take the time as he thought it to be too niche for him (he’s a filmmaker and uses social media for his work as well).
But his first posts got quite some interaction on the fediverse. The usual greetings to #neuhier postings, lot’s of stars and also a bunch of interaction. From my perspective much more interaction than he usually sees on posts on Instagram. And he noticed that too. So let’s hope it sticks 🙂
Learning
FreeCAD – my YouTube tutorial list
GDR had one of the largest fishing fleets to basically make money by selling the fish to western countries.
Reading
Still reading “Manual for Cleaning Woman” by Lucia Berlin. Was reading at least a few pages every day.
new books added to reading list (pile of shame)
- “The Serpent and the Rainbow” – because
- “Der Tägliche Stoiker”

@holly
you could do what I do and just follow folks that post cool #blender projects. I don't post much yet but I'm working on learning #freecad to make precision assets for blender.
right now I'm documenting an #aquaponics project at #pasca (a community garden in CA USA #sfba )

A definite quality of life improvement in FreeCAD was to set the sizes of the points in a sketch a LOT bigger. The default is 5 px which on my 4k screen was about 0.2 mm and almost impossible to hit. Trying to set up constraints was so bloody frustrating as lining up the mouse pointer on a point took ages. Much better now, could go even bigger than 20 px.

První test fit úspěšný! 🥳
Ještě asi proběhnou menší úpravy předního panelu, ale pomalu můžu začít slavit 😅 Reprint kvůli špatnému designu se týkal jen jednoho dílu 🙂 -
