Byteborg's Direct Drive Extruder (3mm)

Moved, look here: https://www.printables.com/model/336820-byteborgs-direct-drive-extruder-3mm

This is my version of a direct drive extruder.

You will need to strengthen the part with the spring-loaded lever, if you want to use it

Sources are included - please, send me your modifications.

It is optimized for the following aspects:

• dead simple, no unnecessary parts
• low profile, maximising effective print height on my prusa
• easy operation, spring-loaded mechanism for easy load/unload
• easy to build

The source lives at https://github.com/byteborg/mendelparts/tree/master/parts/direct-drive-extruder and you are welcome to play with it.

Update version 0.2:
Added a part to hold the bearing in place (bearing_clip.stl)

Update version 0.3:
Sturdier extruder body

Public Service Announcement:
Print the roller lever in ABS, and print it twice :)
PLA is too brittle and will break after mangling a few kilograms of material. You want to have one of these in spare.
Perhaps I'll redesign the lever shape a bit, in case it troubles me too much.

Public Service Announcement #2:
Do use DRV8825 stepper driver for added torque ;-)
