Summary

This is a modified version of BMG extruder to reduce filament travel to minimal. You can use original or clone Mosquito hotend, or a Crazy with it.

Mount for MGN12H included.
Now comes with an other mount that requires 6 M3 nuts and screws, but can be disassembled without needing to disassemble the whole X axis. For this, use the new_mgn_mount files.

Dual 5015 blower cooling duct included, check your machine before assembly, might collide with your frame.
Step files available soon.

For heatsink cooler you will need a 4010 blower.
You will have to use internal parts(bearing, gears, rods) from a BMG(or spare parts for a BMG). For motor mounting you should use the stock BMG screws. For the mosquito/crazy mounting you will need the stock M2.5 screws. Mounting the fan duct requires 3pcs of M3*10mm screws and an M3 nut. You need to print 2 pieces of the nut holder, place M4 nuts into motor side of the extruder and push it in with the holders. On the other side, you can just slide the nut it.
Custom base might be required to use this with your machine.
