QT Py 卡扣盒

Nice design.
Printed black and white PLA+, worked well until left in closed greenhouse during heatwave causing one of the units sides to bend/deform.
Tried one back in TPU (shiny one), will print more in PETG, but want to think about cramming more sensors with better separation and optimised airflow / sensor-exposure. Need a few more to tame the QTPY jungle...
