Build Plate/Bed Cleaner and Origami Pinwheel

Build plates get dirty over time, and some stains are surprisingly stubborn. They can appear at the bottom of prints and are especially noticeable on light-colored products. A quick fix is to print a thin square sheet over the stained area—peel it off, and most of the residue comes with it.

Printing a full-plate sheet takes time, but it becomes waste the moment it leaves the bed. Instead of tossing it, I added a few holes and slits and turned it into an origami pinwheel (see images for assembly). It’s a bit large to spin by blowing, but waving your hand works fine, and it can even be hung by a window.

Scale it to fit your build plate. Just tune the layer height to ensure the sheet is sliced into at least two layers, which improves strength and layer bonding.
