For a school project I made my first ever perfboard, and the L298N motor driver needed to live next to it. Until now they were both sliding around in the box like two strangers in an elevator, so I designed a 3D printed tray that holds them side by side. The wiring between them stays short and the boards stay put.

It fits a 81x51 mm perfboard with mounting holes spaced 1,4 inches apart. and a standard L298N module. Raised posts keep the boards off the plastic, and both are screwed down.

Printed on a Bambu Lab A1 in PLA Basic, 0.20 mm Standard profile, about 35 minutes. PETG is better if it sits somewhere warm.

About the soldering: it is my first one, so please look at the tray and not at the joints. They hold, which is the nicest thing I can say about them :).

Small confession: the L298N mounting holes are M3 size, but I only had M2 bolts, so I modeled it for M2. They fit with a little play.…
