Tedro Remix - Unified Prusa i3 Extruder for Mk8 drive gear and e3d v6 hotend

thingiverse

This is a remix of thing:1277720 Sorry about the quality of the photos... I really liked inornate's "Unified Prusa i3 Extruder" and printed it a long time ago. I used it until now, and everything worked very well. Overall, this remix should: Require less time and material to print Be easier to print (although one support is needed) Be smaller and therefore more stable and stronger Be compatible with the original version (except for the Extruder Tensioner) Cons: No place for M3 nut on the Extruder Tensioner hinge. There is no need for the nut, though. Over time, I figured out a few ways to improve the design: No need for the spacer - it's already part of the extruder. Also, the part that holds the motor is moved upwards (if laying flat) to reduce the need for the spacer. Therefore, one support is necessary. The whole upper part (motor mount and extruder tensioner) is moved downwards (if the extruder is mounted) by 2mm so there is a smaller gap between the X carriage and the E motor. A hole for the Tube Clamp is deeper, so the clamp can hold the tube more firmly if you need it to. The E drive gear was sealed from the right side, which was an issue for me so I "opened" it. The original version had space for two screws to adjust the extruder tension - I found it okay to only insert one screw, so I only left one hole in the upper part. The Extruder Tensioner is half a millimeter narrower (0.5mm from each side) so it fits nicely even after the Extruder part was changed. Also, there are holes on both sides - for M4 screw head and M4 nut (circle, not hexagon). Finally, the second hole for the screw that keeps the tension on the extruder is filled out. There is no need for it. For the Extruder Fixer - I just made it smaller and nicer. If you need the outer holes which I removed, go ahead and use the original one. Oh and also, I put holes for M3 nut from the bottom - tight fit - so if you disassemble the extruder, they won't fall out. Don't mind the fact that my motor is tilted. It had to be that way on the original version as well. Also, I am aware of the fact that my carriage is upside down. I guess it doesn't matter so I leave it like that. If you have any suggestions, please comment. Extruder's and Extruder Fixer's .dwg files are included. Extruder Tensioner's FreeCAD files are included.
