Scanning surfaces with our Lulzbot Mini

Post by threedee42 » Thu Feb 15, 2018 8:13 pm

Hi everyone,

We use our Mini to make custom light buckets for our RC cars. Creating a suitable 3D model is the hardest part, especially for modern vehicles with curved surfaces.

So we mounted a micro-switch on a cradle, secured that cradle onto the hot-end,
A Python program emits G-code and probes the switch. The program outputs a polyhedron in OpenSCAD format, which can then be further processed to make the finished light bucket. It worked surprisingly well.
This does not replace a real 3D scanner; it is only suitable to scan semi-vertical surfaces.

If you want to play around with it, you can find the code and documentation on Github:

cheers, Werner
