Render tile adhesive trowel applicator

thingiverse

Print upright, snap off the support, and attach a bit of of corrugated plastic as the handle, and now you have a good way to spread tile adhesive or render or plaster or anything else you need an even layer of on a surface. Works surprisingly well printed with a single 0.3 mm wall and 5% infill, coming out to just 11 grams. Print double-wall if you want it more robust.
