Creality Ender 3 Top Mount Bowden Extruder Bracket

thingiverse

A simple bracket to mount your bowden extruder on the top rail of your Ender-3 or other v-slot mendel type printer. This makes it easier to change filament without accidentally messing up the Z axis, works well for me with side/rear mounted spool (such as https://www.thingiverse.com/thing:4333835) and it should reduce the amount of flexing in the bowden tube especially nearest to the bed. In the case of upgraded extruders such as the one I have installed it also prevents fouling on the Z axis lead screw. Can also be used vertically, as shown, I found this was even more convenient and means the bowden tube cannot rub on the top bar. Requires 2 x M4 screws + T nuts the same as those used for the factory spool holder (one should do at a pinch) I would suggest using PETG or ABS but PLA should work, as the motor effectively rests on the side of the top rail and keeps it in tension, there shouldn't be too much bending force to make it sag. Designed to print without supports. I recommend using a bridge mode to improve the appearance and strength of the bridges. The extruder in the picture is the BIQU dual gear and makes a nice upgrade to the factory extruder. On the end of the top bar in the 2nd photo is this filament guide which I designed for the purpose: https://www.thingiverse.com/thing:4753086
