Version 2 released: http://www.thingiverse.com/thing:1632847
If you have a Prusa i3 and are upgrading your hotend to an E3D v6 with Bowden, then you'll need this hotend mount for your X-carriage.
As this design clamps the hotend to the mount, there's no chance of a wobbly hotend.
NOTE: Added dual fan mounts with fan duct
21 May 15 - Added 'clone' carriage and clamp for non-genuine E3D hotend
28 Jun 15 - Added carriage clamp with side blow fan mount
2 Parts - The carriage and the clamp.
Print both at 0.2mm with 30% infill.
To clamp this unit together, you'll need 2 x M4 screws with 20mm length and 2 x M4 nuts.
Fan option added:
You can now attach a 50mm fan on either/both sides of the carriage clamp.
Side Blow Fans also ;)
