Lead screw nut
thingiverse
Initially, I printed a nut for the lead screw (RS part 703-9389). However, screw nuts are currently on a one month delay. The printing process took only 20 minutes and has been running smoothly for a month. Although concerned about ABS durability, replacement parts can be easily obtained from RS. I faced difficulties uploading images but will try to add better ones later. For the next print, I may skip shelling as it was done to preserve plastic and before mastering printer operations.
