BMG conversion (direct/bowden)

Edit: don’t use this thing, it’s super old! Use afterburner instead.

Yet another BMG to prusa-style extruder conversion. I did not like stock BMG idler mechanism so i stole design ideas from mobius2 extruder. You cam make both direct or bowden versions. For source parts i used chinese Triangle Lab clone. Things you need to take from it:

• bondtech style gears
• big and small gears
• spring
• all bearings
• m3 screws
• shafts

Custom mount for hypercube evolution included. Mounting uses 2 m3 screws vertically spaced by 24mm.

Feaures:

• Adjust tension
• Lock/unlock with latch (stolen from Voron Mobius2)
• Cutout to see the nozzle
• Izi duct dismount for quick access to the nozzle
• As compact as possible

BOM:

• TriangleLab BMG extruder
• m3 screws:
• m3x20 x 2
• m3x10 x 3
• m3x35 x 3
• m3x30 x 1
• m3x20 x 1
• m4x12 x 1 screw or e3d thumbscrew
• m4 nut
• m3 nuts x 5
• 5015 radial fan
• e3d v6
• pancake motor nema17 (standard nema17 won't fit direct version, bowden is ok)
• 40mm fan
• nema17 PTFE gasket

Designed are to be printed without supports, but i am lazy to reorient parts properly. Idler part require support, sorry for that.

Designed in onshape. If possible use parts directly from onshape beacause i constantly tweak some stuff. Link to source:
