NeoPixel Pop Bumper Caps

Post by spierepf »

Greetings,

My Makerspace team and I are building a pinball table, and we have printed our own 3D pop-bumper caps. You can find the designs at:

https://tinkercad.com/things/0dyVlFUBkrd
https://tinkercad.com/things/eM41eBnHvJA

If you flip the caps over, you will find twelve square recesses intended to mount NeoPixel 12 rings: https://www.adafruit.com/products/1643.

Unfortunately, the recesses aren't quite right to properly fit the device, and I was wondering if there was any place I could get an accurate dimension drawing of the ring to get the fit exactly right.

Peter.

Nice work!
The CAD files for the rings are here: https://github.com/adafruit/Adafruit-NeoPixel-Ring
For tight tolerances like that, shrinkage may be an issue. Have you calibrated your printer to account for shrinkage of the plastic as it cools?.
