I adapted this model for the one in the QUBE 500 because 2 were missing from the box.
scale at 99% if they are too tight
print with a brim if usually small parts don't stick on your bed: I used ASA at 0.12 with a 4mm brim.
a good idea could be ABS, probably PLA is too rigid but I didn't test.
The author remixed this model.
