Holds 3 motors in a clamshell

thingiverse

Designed in Tinkercad, this project requires one to three small parts and one clamshell. On my printer, the cube parts measure approximately 9.05-9.20mm square, slightly off from the 9mm specified by Tinkercad. The clamshell's design called for 9.30mm cubic holes, but my printer produced 8.8-9.15mm holes, necessitating a scale-up. Printing both STL files on a Monoprice Mini Delta with a relatively accurate extruder should result in small parts fitting snugly into the clamshell and it closing completely. Sanding the faces of the clamshells is recommended if necessary. Supports were used during the printing process for the clamshells. The small parts are designed to house 3V 1400 RPM "cell phone motors," commonly employed in brushbots, which measure 5mmx5mm on their case and approximately 12mm from back to tip. The hollow interior of the small part housing accommodates the entire motor, with a semi-sphere added to account for the potential larger diameter of the motor's shaft. The wiring channels might be too narrow, but this was just an idea that took two and a half hours for the first failed print and another two iterations to produce the final .stl file.
