Gear for ghagen01's Ultimaker extruder update by DeuxVis

Last crawled date: 3 years ago

An Ultimaker extruder big gear, for attachment on a non-threaded shaft.
This is an accessory for the Ultimaker extruder update by ghagen01 rather than a derivative.
It is needed if you have produced a 50materialwheel part without threading on its shaft - printed at shapeways in steel for instance, rather than machined.
By the way I uploaded the 2 metal parts on shapeways :http://www.shapeways.com/model/530334/http://www.shapeways.com/model/530335/
Update :
V2 is beefier (previous version was prone to flexing) and has better designed nut holes (nuts were tending to rotate).
Also from my experience, it's a good idea to have a bump drilled in the axe to allow one of the M3 bolts to avoid rotation.
Update :
V3 is stronger around the M3 nuts - the plastic here was prone to cracking when tightening too much in order to avoid the gear slipping on its axis.
