Panel holder - join two pieces together

If you want to join two pieces of 3D printed panels together - use this - also here's the OpenSCAD code - where you can adjust the sizing yourself and then print it to your sizing.

Change the thickness of the 'grab part'

Print it about 15 percent infill - to grab a 5mm piece, I made the thickness 4.9mm - allowing the panels to slide into it

The OpenSCAD file is uploaded as well, help yourself
