Lego Mindstorm / Technic Part Designer

As the customizer isn't working right now, please visit https://www.aposteriori.com.sg/lego-mindstorm-part-builder/ to design your Lego Mindstorm / Technic parts.

Unlike other existing Lego part customizer, this one allows you to easily design (almost) any shapes and configurations. The uploaded STL shows some of the example parts that were designed using this tool.

I've also uploaded a SCAD file. This is an earlier version that I created, and it's largely identical to the web-app version.
