Mini Extruder for E3D Hobb Goblin (Tantillus Reborn)

Remix of the original extruder for the awesome Tantillus Reborn by Lars.

Check out www.scheuten.me for the Tantillus R project!

I didn't like the original extruder with the MK7 gear and squished bowden tubes.

So I remixed the extruder to be able to use a regular PC4 push fitting and the grippier E3D Hobb Goblin gear. The extruder consists of 1 Body, 1 Cover, 1 idler and the acrylic lid (optional).

How to:

Use the screws, bearing, springs etc from the original extruder, add 1 x PC4-M6 push fitting.

• Insert M3 nut into nut trap, insert screws and spring (like in the original assembly)
• Insert the lever with the installed bearing.
• Slide a short piece of ptfe tube into the extruder body from the bottom right up to the inner housing, it will hold due to friction.
• Pre-thread the top hole with M6, screw in the push fitting and insert bowden tube until you reach the inner housing
• Put on the lid and the acrylic plate (from the original extruder)
• Screw it to the Tantillus enclosure
• Don't forget to adjust the e-steps for the new gear!

BOM for those who don't have the original extruder:

• printed parts
• MR105ZZ bearing
• 4x20mm cylindric metal shaft
• PC4-M6 Push fit
• 1 x M3 hex nut
• 1 x DIN912 M3x20
• 1 x DIN912 M3x8
• 1 x DIN912 M3x30 (possibly shorter if you dont use the acrylic lid)
• 1 x 0,8 x 4,7 x 20mm spring (or similar dimensions)

The outer part doesn't need support neccessarily (depends on the bridging ability of your printer) whereas the idler needs support for the bearing mount
