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.

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.

Damn. I forgot I broke another of my v5 25° 3D printed Seestar lens hood/light baffles on Tuesday night so tonight the Thirty Millimetre Telescope is wearing the ludicrously large v5 20° design.

These things are getting broken at the end of the night when the Seestar automatically closes the telescope arm, bending the push-fit lens hood out of the aperture and causing it to drop onto the concrete patio below.

The weak point is where the narrow cylindrical section that fits inside the Seestar aperture meets the top of the conical section. The walls are as thin as I can make them at that point because any additional thickness right there intrudes on the telescope beam, losing light. Compounding the issues are the fact that these are printed in matte black PLA which is rather brittle, and they were printed when it was very cold inside the house wasn't doing the layer adhesion any favours.

I don't know whether they're breaking when the telescope is forcing them out of its aperture or when they hit the ground. For now I can reduce the length of the cylindrical section to reduce the moment arm when it gets nudged out and add a loop so I can tie a safety harness to the lens hood to stop it dropping all the way to the ground.

Longer term I can try printing them in tougher filament (I have a spool of PETG-CF I bought for this purpose, but need to swap out my brass nozzle for hardened steel first) and switch to magnetic attachment instead of a push fit.

For tonight I'll just turn off the automatic closing function of the Seestar, I don't think the bigger, heavier 20° hood will survive the fall to the ground. As long as I bring the telescope inside in the morning before the Sun can shine into it that'll be fine.

I got the dimensions of the USB-C jack wrong the first time … :eyeroll: But now everything fits fine. The PCB is held exactly in place by the top lid.

For such #3dprinting projects I like those self-tapering screws for plastics. Once installed in my #velomobile with the right lengthened wires, electronics and speaker enclosures will be closed (the later one w/ glue).

Making enclosures and lids fit was easy w/ binders (offset -0.1mm) in #FreeCAD.

… from master sketch to main part of the enclosure.

I just started the 3D printer to check if my tolerances fit the electronic component(s).

Open source tools like FreeCAD are okay for quick sketches, but the transition from traditional CAD is often overrated. The flexibility is there, but the workflow feels clunky compared to what I used for my projects in Kyiv. Most people push it for the price, but for a real architect, the logic of the space matters more than the software license. It is a tool, not a solution for better design.

#FreeCAD people, I need to make many pockets with the same shape. They have to be positioned in specific coplanar positions and orientations that have to be set up with constraints.

What's the best way to do this? I don't want to have unrelated duplicates: editing one sketch should update all pockets.

I ♥️ tidy master sketches in #FreeCAD

I use a PartDesign Body as a container for the master sketches. This makes using binders w/ offsets easier. The "X-ed" rectangles stand for off-the-shelf electronics parts.

Alcuni lavori sono più belli di altri.
Oggi un cliente mi ha chiesto di stampargli in 3d un perno per l'interruttore di un forno industriale da pizzeria.
E io mi ci diverto da matti.
Prendo il mio #FreeCad e me lo disegno, poi lo stampo.
Sono cose piccole ma danno molta soddisfazione.

FreeCAD is broken—well, well, a classic favorite case… Why is FreeCAD broken? Because it’s installed as a Flatpak on Linux Mint. Duh! The fix is simple: just use the AppImage instead . But why the official installation is broken to begin with is a great question. Apparently, there’s some undefined PySide6 symbol error dragging it down. I don’t even want to get started on it. I assume everyone upstream is just pointing fingers at each other. - There’s “nothing wrong”, it just doesn’t work. Total win. The only thing guaranteed here is an extremely bad UX, because things just magically break down when the user did absolutely nothing. Classic. #FreeCAD #Mint #Flatpak #PySide6 #Linux

The name plate was designed in #FreeCAD¹, sliced in #PrusaSlicer¹, and printed on my custom-built 3D printer. Its parts were designed and shared by @bear_lab and runs on #MarlinFW.

The leatherette was designed in #Inkscape, the G-code generated with #KiriMoto, and cut with a custom little #vinylCutter attachment for the 3D printer².

Soprattutto #FreeCAD è incredibile!
