About this 3D model

EDIT: Missing components have been added! Photos added! Small, handy, and easy-to-print sanding block. Width is 50mm, height 30mm. The sandpaper can be easily tightened by hand on the back with the clamping device. However, an M6 threaded insert needs to be melted in, and an M6 hex screw is required that is glued into the knurled nut (2K or super glue) ________________________________________________________________________________________________________________ EDIT: Missing components have been added!
