I really like the original model, but I wanted something that would allow me to not cut the sanding paper along the longer edge, so I came up with this. I had to add more clearance in the adapter plate, because it wouldn't be possible to install it without a hammer. Now it should be much easier. My sanding paper is 91.5mm wide.
If you want to adjust the model for your sanding paper, please contact me :D
The author remixed this model.
Wider block, screw nut adapted for shorter screws, added more clearance for adapter plate
