Freeplay CM3 Cart Cover

So i bought this and dont regret it, it makes it feel a lot more finished (even with the 3d printed feel) if you dont have a 3d printer to print this yourself, or dont have it calibrated well enough to make it, i highly recommend getting it
P.S. sorry cant give a 5 star as nothing is perfect

Lovely addition

Lovely little addition to the cm3
