This is a Wall Hanger for displaying your custom keyboards.
It should fit most of the keyboards, see photos of my 65% (Gamakay LK67 / TM680), 45% (Handmade custom for Rafi RS 76 M Switches) and also tested with 60% GH60.
The only thing I cannot verify if fits keyboards with function row or 65-75% with big edges (like Keychron Q1 or Q2 or GMMK PRO)

Fix the hanger to the wall using M3 (which I used) or M4 Countersunk srews.
