Jig for Infinity Cube / Hyper Cube

Jig to help soldering LED strip corners when making hypercube such as https://www.thingiverse.com/thing:5144041
The third photo shows the LED strip upside down just to convey the principle more easily. For the actual cube the LED strips obviously need to be face down

I added a cut down version suggested by https://www.thingiverse.com/badkitty/designs
