Resized bearing housing and added a personal touch to Thomi3D design inspired by vilove one.. It should work, please refer to original designs if you have particular needs (the spool somehow doesn't place itself on the vertical bearing).

UPDATE: upload V2 with longer arm and space for 3 bearings and the one with no bearing that works as normal stopper

EDIT: V3 introduces built in stopper abolishing central one thanks to fred_blond that inspired with a remix with another bearing that comes with a builtin washer

Claw was resized a tiny bit

PLEASE NOTE ALL: this is a concept, it works but it is meant to be used as idea, it contains not manifolds that does not affect print

Feel free to fix it trough meshlab /meshmixer as i am too lazy to do it, and i am not mary poppins
