Yes, I designed a small upgrade for a 12 year old printer. I wanted a vertical x-axis similar to the Prusa MK4, however the hardware I have on hand is from my old Mendelmax, specifically;
16mm brass bushings for the vertical guide rods
38mm delrin leadscrew nut
8mm x-axis smooth rods
Besides the above, the main differences are additional clamps for the rods and bushings. I also added a tensioner for the belt using a M5 bolt and nut.
I designed the tensioner for a 22mm bearing, which is what I have on hand, which unfortunately means that the belt path isn't perfectly straight to the pulley. However I can accept a ~0.1mm deviation over 250mm. The clearances are pretty tight, but everything should be able to pass through each other without crashing.
Some supports are needed, which I just designed in, should be easy to break off using needlenose pliers.
I don't have a working printer at the moment, so I'll have to pay to get this printed before I can test it. If you find any mistakes, please let me know!
