I am making an infinity Cube with glass panes. After many different ideas on joining the glass, i realized the more simple things are, the better they work.

Very simple, the glass slides into the channel. Leaving a 3mm-4mm distance between panes.

I uploaded 2 different sizes. One for 2mm glass, one for 3mm plexiglass.

Step file included so you can create for different sized glass\plexi.

This does not have a pointed tip, as that meant you'd need support on the bottom channel when printed upright. So it's oriented in a way that prints great, no supports and gives a nice flat corner, instead of pointed.
