Adjustable Feet - Ender 3 Pro - 4040 Aluminum extrusion

thingiverse

After printing FedorSosnin's design a few times and realizing it did not fit my printer's aluminum extrusions, I decided to measure my extrusions and create my own design. This was done on an Ender 3 Pro (August 2020), so older Ender 3 Pros are not guaranteed to work with this design. I've included the files with the file ending "tight_tols" to indicate the design I printed and was happy with, although it fits snugly on the aluminum extrusions and the screw threads might be tight on the first attaching them. If your printer has difficulties with repeatable precision or overextrudes, I would recommend using the other files with the file ending "loose_tols" that have a bit more play and are more likely to fit (possibly loosely if your machine underextrudes).
