Modeled after a DuraBlock hand sanding block. They measure 2.75 x 5.5 inches. Designed for 2-¾ inch PSA (sticky back) or hook-and-loop rolls of sandpaper. Just add some velcro to the bottom for the hook and loop.
The work great printed in TPU with 6-10% gyroid infill so they have a little squish.
If you're slicing with BambuStudio or OrcaSlicer and would like to print it with MMU, drag and drop the Dura Block Debossed and Dura Block Text files at the same time to be loaded as one model. Then assign a different spool to the text.
I've included an embossed version and a couple .STEP files as well.
The author marked this model as their own original creation.
