Giá đỡ giấy nhám (Support for sandpaper)

This model comprises three parts, easy to print without supports. Assembly requires an M3 screw and nut. 

Assembly instructions:

1. Print the parts (suggested: lower layer height for smaller pieces)

2. Insert the nut into the hole and the screw into the thumb screw grip (if the fit is too loose or too tight to assemble, heat screw/nut or use super glue).

3. Cut a suitable sandpaper piece and assemble all components together.
