grabcad

This is a filament guide for the Ender 3 V2 printer. The guide aims to reduce stress on the filament, straighten out the entry into the extruder, and avoid rubbing against the z-axis screw. This is an update to a previous design using heat inserts and a bearing. This design improves ease of printing and requires no supports.Revision Log:Revision 1.0 - Works fine but found it was difficult to unload used filament due to the bulge formed at the hot end. Also the snap axle was prone to breaking during removal of pulley if ever needed.Revision 1.1.-Increased diameter of slot to 2.5mm to improve ease of removing used filament.-Improved profile on snap axle to make stronger and easier to install.-Increased thickness of base flange from 2 to 3mm to improve strength and rigidity
