Pulley Remover

thingiverse

This is a simple and easy to print pulley remover / puller. It can be used to remove pulley from motor shaft or to remove bicycle chain-rings to name a few cases. - Bolt spec is M16, if you already have one you might not need to print puller-bolt.stl - I provided a an adaptor for a 8mm motor shaft and an "Arrow head" adaptor as well. ### Printing Instructions - Prints are already oriented in the optimal position - None of the parts require supports - increase number of wall (4+), top layersand bottom layers to add strength to the part - Print puller-arms.stl with 100% infill - puller-bolt.stl is a slightly longer print compared to the other 3 parts. - puller-bolt.stl might be good to print with a brim ### Weaknesses/Future Improvements - The weak point is the hinge - A version with 3 arms and with 4 arms would be good ### Updates - Added a version with 4 arms
