Y Axis Linear Rail Mounts

thingiverse

Want to do a linear rail conversion on your y-axis? You got it! This setup uses two 400mm MGN12H linear rails with three carriage blocks attached to the bed, set up just like the Prusa i3 MK3. The ones I bought were for use with M3 hardware, but there will be larger versions available for bigger hardware soon. After testing this out for about a month now, it's not really a print quality upgrade, it's more of a quality of life upgrade for some, and a "because I can" upgrade for others. I usually print at 100mm/s so maybe it'll help with increasing speed, but I was doing that with rods too. You'll need: - 4 printed linear rail mounts - 8 M5x16 bolts, these were extras from the RepRap build - 8 t-nuts or HTNAJ5 nuts to insert into the extrusion and tighten down using an M5 bolt - 12 M3x? bolts for the carriage blocks (or M4 or M5, whatever yours are) preferably if you can find M4, use that since that's what's already being used on the stock setup - 4 more M3 screws and 4 Nylock nuts for bolting down the rail to the mount - possibly a Dremel, since the holes on the carriage blocks and the bed holes didn't quite line up for me - patience. Lining up these rails is tricky, and any deviation will be noticeable due to the higher precision that comes with rails.
