Half-case for NUCLEO-L552ZE-Q with breadboard pockets
Tray for the NUCLEO-L552ZE-Q (Nucleo-144, MB1361) with pockets for a 400-point half breadboard and a 170-point mini breadboard.
Hole positions were taken from ST’s PCB design files opened in KiCad, since the mechanical drawings in the user manual are incomplete (the holes are not symmetric). The FreeCAD model is included, with all dimensions in a spreadsheet, so it’s easy to adjust tolerances or adapt it to another board.
Other Nucleo-144 boards use the same form factor and may fit, but I’ve only tested the L552ZE-Q.
Print: sage-green PLA, 0.6 mm nozzle, about 1 h 45 min on a Bambu Lab A1 mini, 77 g. No supports needed.
Notes: The tolerance for the mini breadboard pocket could be a bit tighter, but it’s good enough. The Nucleo wiggles slightly. You can remove the middle pin using pliers or add a few drops of hot glue.
