When spreading grout for tiling in areas like the kitchen or bathroom a normal tool may prove to be to large and unwieldy. My landlord asked for a cheap 3D printable tool that could fufill three tasks. The first main taks and what this tool is made for is spreading grout for tiling. However there are two other functions that you can use this for: smoothing concrete, and spackling. Those secondary applications won't work as well as a dedicated tool but this tool can still perform them. And as a bonus function you can table sandpaper to the bottom of this and use it as a sanding aparatues if you are lacking a powersander!

Dimensions: This is a small trowel designed for tight areas. The notches are.25in by.25in. LxW 6inx3in
