A desk valet I made for my stuff. 7x7" with space for keys and stuff, change, my wallet, pen/stylus, and phone charging station. Printed in wood PLA. Filled with wood putty to smooth out the layer lines, sanded, stained, and finished with polyurethane. For a smooth finish I cleaned the final layers of poly with micromesh and polishing paper.
I also made a silicon mold of the base to cast some concrete versions.
