BMX Sprocket/Spindle Adapter (parametric)

Needed an adapter to mount cheap sprocket from AliExpress on girlfriends dirt jump bike. Model parameters are set for Norco One25 which uses a bmx “mid” style bottom bracket with 19mm crank spindle. 

Testing with PLA first, but will definitely want to up to at least PETG, probably better with ABS/ASA. That said this might just be a part to consider a consumable anyways.
