3D printable piece, designed to work with the flywheel puller metal part made by Fetteworst, to pull any Daybreak, Kepler or Pulsar wheels (or any other wheels with the same top geometry) off a motor shaft, without risking bending the motor shaft, or applying force to the flywheel cage.

Metal part can be found here: https://www.etsy.com/listing/744330014/nerf-flywheel-puller

Flywheels are sold by Kuryaka through Etsy, and various resellers (FoamBlast, Out of Darts, Blaster-Time.eu, ...): https://www.etsy.com/shop/KuryKafe

M5 hex nut included with this should be a nice friction fit in the printed part. Slip over top of flywheel, rotate metal part (internal hex driven) to pull the flywheel straight up off the motor shaft.
