Revisited this idea today and topped off the cube-jar with an M12-1.75 thread, modeled with #BoltGen in #Rhino3D and then physically cut into the correct geometry using the M12 die from my cheap metric tap-and-die set. That seems to have worked, so next up is a matching lid with a thread to be cut with the same kit.
This was also printed with random seam placement and scarf joint seams - that seems to work well these days, leaving an interesting but not undesirable texture. #3DPrinting

#Hippo3D also looks very promising, here you can download the add-on for #Blender, it is still in the early stages of development.. #CAD #Rhino3D #Blender3D #b3d #Nurbs

And here's another video, again from a different #Blender3d user, doing something I've always dreamed of seeing in Blender. This time another user, Victor Calixto, has built a #CAD NURBS modeler called #Hippo3D that imports and exports STEP models and imports #Rhino3D files. Man, I think the near future is gonna be awesome for #b3d #CAD users.

Here's a cool 3D printed thing I saw on Reddit.

making a hex key holder for my bandsaw and realizing there's a somewhat cursed shape involved. I started by making a simple tube sweep as the key to subtract from the holder, bent 90º so I could have them sit in little pockets.
But if you just do that, you end up with the top of the slot rolling back over itself, and you couldn't get the key out. Fine, just extrude another cylinder up further and subtract that.
But then there's still this little pinched in area between the straight tube and bent tube that needs to be handled with an extrusion from the bend radius and the centerlines of the strait sections. I beat Rhino3D into making this shape, but it was hit and miss. I'd love to figure out how to make this parametrically but I can't figure out how to describe that little inverted 1/4 of a circle.

back on the bandsaw repair:
I've fully quantified just how cursed this arbor is. the hole in the back was drilled at a slight angle, this is the hole that slips onto the motor shaft, so the arbor has a wobble.
The threaded hole that accepts a bolt & washer to hold the wheel on is straight, but drilled in the center of the bottom of the angled hole, so it's offset.
I did a small test wheel attempting to counteract for these shenanigans, and it mostly worked.
I'm gonna try it on a full size print next. We'll see what it looks like in the morning!

3D printed shims for the win!
This bandsaw came without its stamped metal feet, which made up for the angle in the casting.
This is the kind of stuff I’m excited to have a printer for; little utilitarian problem solving accessories.

Here's a behind-the-scenes on the process.
In the same way a woodworker might use a jig on a table saw to get consistent, repeatable cuts, I use a virtual jig to get consistent and adjustable subtractions on my model. The magenta thing in this screenshot is that jig - I just generate a bolt, cut it with the subtraction jig, and I have the shape I need to print.
That jig is made up of six different objects I can tweak independently to make iterative changes to the design.

SubD are handy for modeling hulls, but trust me, nothing beats #SurfacePsycho when it comes to #CAD #hull modeling. Not even #Rhino3D or any other CAD software comes close to what Surface Psycho can do. #Nurbs #b3d #Blender3D #Blender #boat #design

These are some mechanical #3D models I made back when I was working in the #mechanical #engineering field. I created them with #Rhino3D 2.0, at the time I had zero experience with the software and taught myself just by reading the user manual that came with it. The company actually bought Rhino on my recommendation; before that we were all using AutoCAD, and I’d only been messing around with Blender for a few months. Back then, not many people in the mechanical sector were using Rhino. #CAD

Okay, yeah. That's #Rhino3D version 5 (because I own a license for it) running apparently flawlessly on #Linux Mint, by way of #WinBoat - and it was close to effortless to set this up.
Rather than futzing around with Windows libraries and trying to run things more or less on bare metal like Wine does, WinBoat sets up a virtual machine with a whole-ass installation of Windows 10 or 11, and gives you a 'porthole' of sorts to individual applications as you run them. It's actually pretty elegant.

I've taken a low poly approach to modeling equipment for layout purposes. I try to get each one done in like 5 minutes. I measure each one by hand with a tape measure, to the nearest 1/8" (because I'm a dumb american and still use fractional freedom units).
I'm working in Rhino, and I make a 3D solid of the device, with rounded corners as appropriate, and often a separate face plate.
Then I grab the most orthographic photo of the unit I can find, paste it into a separate layer, and lock it. I trace only the most prominent and basic elements; enough for it to be instantly recognizable by me, but without going of the trouble (and overhead) of modeling every connector.
I'll make custom colors for objects using the color picker.

All I've done to get this result is to draw that exact shape in #Rhino3D, use the SaveAsSVG plugin to export it, manually copy the d="..." string to both the "board" and "silkscreen" sections in the PCB-ready SVG.
...With one extra step - I altered the "viewBox", "height" and "width" fields to get it to display fully in Fritzing - otherwise it cropped it to the same 40x20 rectangle from the first test. JLC probably doesn't care about those values, so setting them liberally might be a solution.

Modeling something like this is simpler than you think. I use #Rhino3D and a plugin called BoltGen to generate an M20x50 thread (with a 2.5mm pitch), shoved an inverted truncated cone on top, and messed around with subtracting bits from the top until it looked about right.
The 20mm width is mainly to make it print reliably - something this tall but less wide would be more likely to break off mid-print, and I didn't want to spend time reprinting a joke.

I think I've entered a new phase with my #PCB design skills. Being able to sketch the layout in #Rhino3D where I'm relatively skilled, then export as SVG and then just line up the handful of actual components just so in Fritzing has been great.
Today I've discovered the existence of "single line" or "single stroke" fonts - apparently used in engraving, but also useful for text on PCBs. The one I'm using here is "MecSoft" from the Rhino people themselves: https://wiki.mcneel.com/rhino/engravingfonts

Quick note on how I design these #NES controller breakout PCBs. I've not made a "footprint" that is natively understood by #Fritzing or other software as a part, what I'm doing is exporting the vector drawings from my 3D model to SVG (for other users of old versions of #Rhino3D, you will want to install SaveAsSVG: https://www.food4rhino.com/en/app/save-scalable-vector-graphics), adding that as an image within Fritzing, and carefully aligning headers and other holes to that image.
