Missing z-butt.scad library

When opening the examples they give the error "Missing library z-butt.scad", which seems not to be included here.

You can download the z-butt.scad lib file here, and put it in the main directory with the other libs and it should work:

Trying to find STL files of DES Row 1, 2, 3, 4 and 5

Does anybody have stl's?

Stem rotation not working in Choc_Chicago_Steno_Thumb.scad

When trying to render keyID = 4 in the Choc_Chicago_Steno_Thumb.scad with stemRot = 90, using all other default parameters - I get some layers that are not rotated.

Adding the rotate transform to the line with the skin() function rotates them and the keycap renders much better.

This isn't perfect though, as the stems now do not sit inside the rectangular base created by the skin() function. But they look connected and would likely print fine (not tested yet).

See attached pull request for a quick & ugly fix.

Cross is too loose

Hi, ive generated the files and printed using resin printer (Elegoo), but the cross of the keyscaps it's losse, it doesn't hold on the switch.

I'm not not a expert of scad files and i don't how to customize it, so if any one could help me making the cross tighter it would be really nice.

I've tried to debug the scad file/code but it's just some really new and different lang and concept of design 3d with code for me.

:)

Printing in MJF nylon

Hello, first of all that's a really nice project.

Since jlcpcb started receiving 3d printing orders, I wanted to get a set of keycaps printed by them in MJF nylon. Anyone has tried that with success? Or will I be the guinea pig?

Step / solid bodies?

Any method to easily get solid bodies for work in fusion?

I've tried the freecad to step solution but it's done nothing but hang.

Help on how to 3d print these

Hi there, I'm trying to get these printed on an FDM printer with a 0.4mm nozzle, but I'm running into various issues.

Because the stem is slightly offset (why?) I'd need to turn on supports, but these then are hard to remove again and they are not needed for the bridging on the top anyway (and I haven't found a way to stop all supports at a certain z-height (yet).

Printing them upside-down avoids that issue, but then the top-side comes out ugly (with supports).

The stem is pretty thin/fragile anyway with such a setup, do you recommend a resin printer for these?

I've also tried extending the stem down to the build plate, but this also doesn't work without supports, as it starts with the 4 tiny corners and they don't hold on to the build plate.

The last issue can probably be fixed by adding 4 spans at z=0 that connect the stem corners to the side of the cap and can be snipped at way after the print is done. wdyt?

Model not generated

Hello,
i am a openscad newbie. If i open the DES_ChocChordCaps.scadfile, i get a lot of warnings and the model is not generated.
I installed this scad-utils libraries.

Where are the lateral column keys?

I've printed a set of DES keycaps before for a TBK Mini. However, I want to build another version, that has the lower keycaps + lateral columns. I'm sorry if this is just a dumb question, but I'm just not sure about which caps are which. I'm guessing these:

PseudoMakeMeKeyCapProfiles/MX_DES_Thumb.scad

Lines 84 to 87 in e32c51a

	[17.16, 17.16, 6.5, 6.5,10.55, 0, 0, 9, 0, 0, 2, 2, 1, 5, 1, 3.5, 2, 2], //R4 8

Is that correct?

Thanks for DES and CS in general! It actually motivates me to look into CAD myself, which I successfully worked around in the past 😄
