BMG conversion (direct/bowden)

thingiverse

Yet another BMG to Prusa-style extruder conversion. I didn't like the stock BMG idler mechanism, so I stole design ideas from Mobius2 extruder. You can make both direct or bowden versions. For source parts, I used a Chinese Triangle Lab clone. Here are things you need to take from it: - Bondtech style gears - Big and small gears - Spring - All bearings - M3 screws - Shafts A custom mount for Hypercube Evolution is included. Mounting uses 2 m3 screws, vertically spaced by 24mm. Features include: - Adjustable 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 okay) - 40mm fan - Nema17 PTFE gasket I designed this to be printed without supports, but I'm lazy to reorient parts properly. The idler part requires support; sorry about that. Designed in Onshape. If possible, use parts directly from Onshape because I constantly tweak some stuff.
