This mount is designed for use with "Compact Bowden Extruder, direct drive 1.75mm" by Schlotzz. (http://www.thingiverse.com/thing:275593) on the Anet A8 Prusa i3 clone. It may work with other printers such as the OMNI M505, etc.
This mount is placed high enough on the machine that you can easily put the acrylic spool stand that came with the printer underneath it.
The part is not actually curved as shown in the picture, the print lifted during the initial prototype, however the warpage did not affect the final dimensions. I have already fixed the location of the hold down for the Z-axis rod.
Designed to use the spare 18mm M3 screws and M3 nuts included with the printer.
You are welcome to modify this part to suit other bowden setups.
Please post an "I made it!" If you print this, I would love to see how it works out for everyone else.
I'm not an expert on printing settings yet, I just used 40% infill for rigidity, Use what works best for you.
