Poor Man's Linear Rail X Carriage

thingiverse

I wanted to upgrade my X axis to linear rails but I was heavily invested in the 3 wheel x-carriage. My entire hot end has evolved around it and I did not wish to give that up. Nobody has made anything similar or at least I've not found it. One would think that dropping a $20 MGN12H on the 2020 would be a common upgrade. The rail I used was 300mm. The block is 46mm x 27mm x 10mm. It uses M3 screws on both the rail and the block. I used M3X12 to secure the carriage to the block. For the rail I bored out the holes to M4 which is a PITA so buy some M3 and equivalent T nuts. I have a drill and I'm impatient, don't be me. Ensure that the screws are below the surface of the rail and that your rail slides freely. It should fall when you hold it on the side. If it hangs you may need to rebuild and clean it, there are videos on youtube on how to do this. Although it should fit on the stock flsun pulley system, I recommend you print one of these: https://www.thingiverse.com/thing:3016701 https://www.thingiverse.com/thing:2838019
