CR-10s simple filament roller adaptor - Arianeplast

thingiverse

I use Arianeplast filament for printing on my CR10s and the roll is hollow at the centre with inner diameter of 55mm. So, solutions based on ball bearings (like https://www.thingiverse.com/thing:2186682) do not fit. Also, the thinness of the ball bearings makes the roller unstable and 625 / 608 ball bearing models are too high to have standard support+adaptor entering into the roller hole. So, I decided to design my own model in order any way to improve a bit the standard CR10s support. To make printing easier without support, I dissociated the piece into 2 parts (to be glued together before mounting on the support). This avoids having to manage supports for the groove. You need to print 4 adaptors for a single roller (2 grooves + 2 sides). If you have a 1kg and 750kg filament rollers, you can print a third adaptor (1 groove and 1 side more) and place it in between the 2 supports for standard 1kg roller. Feel free to test and comment :-)
