Hand Sander V1

Hi all,I’ve designed a simple hand sander to help smooth plastered walls before painting. The sandpaper needs to be cut to size, placed centrally on the base, and then secured by pressing the handle clamp down over the top. This holds the sandpaper firmly in place during use.This is a first draft, and I’m planning to refine and improve the design to make it more practical and user-friendly. If anyone decides to print and test it, I’d really appreciate your feedback and suggestions on how it could be improved.
