I can check the relative dimensions between the two and give you a percentage difference...it's not going to be super accurate but it'll be in the ballpark. I know that the height is the same as the ikari sticks at least.

Don't bother with this part, I'm already on it. ;D

Between the extremely accurate measurements in the LS-30 model, these two pics above, and the left stick in this pic, I can get really close.

True. Looking for more/better pictures this evening, I noticed that both the Data East (cylinder) and Wico (balltop) rotary sticks used a split-pin to secure the handle to the shaft.

Found another useful photo here, calculated the variables, and plugged them into the model. ;D
- The measurements look accurate so far, but it would be good to confirm them.

Noticed several things while taking measurements from the photos:
- Upper and lower roundover diameters are very different.
- The upper roundover Z-axis is compressed. The roundover cross-section is wider than it is tall.

The handle file is usable as-is, but should be updated to incorporate these observations.

That just leaves the logo.
- I can haz an exported png, plz? :laugh:

Howard_Casto:
Sure....

I'm not sure about those arrows.... I can smooth them out a little more if need be.

Thanks. :cheers:

The logo processing turned out great. :woot

As hoped, starting from a new Inkscape file and following the step-by-step procedures worked perfectly.

The only minor setback was that vectorizing the original image resulted in a vector group that didn't reach the top/bottom/left/right sides of the Inkscape page.
- Not reaching the sides appears to cause the previously-mentioned X/Y-axis offset problem when importing the dxf to OpenSCAD. :banghead:
- Added a dot in each corner of the png and now it works perfectly. ;D
- For future reference, it probably would have worked with dots in two diagonal corners.
- The dots don't show up in the model because the logo is being subtracted from the round top.

Resizing works great.
- Blew it up to about 9x the default size.
- No problems with logo centering or jaggies.

Seems like the only things on this part that we might want to change are:
- Using a version of the logo with the circle since the seam between the handle body and removable top is smaller than the circle on the original handle.
- I'll edit the current logo to make the arrow-only version shown earlier in the thread.
- The logo might be a bit deep.

Current handle-top source files, code, and STL are in the attached zip file. :cheers:
