BLV AM8 MGN 12 Adapter for Prusa MK3S Style Extruder
Description
This is a Direct Drive extruder mount designed to work with BLV's MGN12 Mod for the AM8 printer. I wanted to add a Direct Drive extruder to my printer. I was struggling to find a good mount that allowed me to use some parts I had left over, specifically my Titan. After spending a good amount of time trying to fit a direct drive, I discovered that there really isn't a good way to mount a titan on this printer due to the thickness of the X-Axis -- it causes the hot end to be too pushed out too far from the X-Axis sacrificing lots of Y-Space. During this time I discovered the this modular carriage which had an adapter for MGN12 (in the correct orientation even!) and the Titan. After printing and tweaking it a few times, I still wasn't happy with the results. At this point, I set out to attach a Prusa MK3S extruder to the BLV mod. This can be had for the price of a plastic plus ~$10 for the drive gears ($50 if you don't want cloned gears). I modified the Prusa X Carriage and the MGN12 adapter from the modular project, and designed a backplat cover with cable management in mind. It should be noted that I have printed this mount, but I'm still waiting on parts to be able to use the extruder. There may be some unknown flaws in the design. I printed this at .2 with 40% infil so it would be strong. It may be a little overkill, but you can decide that for yourself. To install the adapter, print one of every piece except the Belt Clamps, you will need two of those. As far as hardware goes, you'll need the folowing: 2 x M3 Square Nutes - Will allow you to screw in the belt clamp 2 x M3x10 Screws - Attached belt clamps to the MGN12 Adapter 4 x M3x6 Screws - These attached the adapter and the cover to the MGN12 Block You will also need various M3 screws (from 10mm all the way up to 40mm!) to build and attach the MK3s extruder.
