I felt the ESCO 3 Ton Jack Stand had too much play/wobble so I created this insert to tighten up the tolerances.  I created the SCAD model with the help of Gemini.  You could easily mod this for another brand of jack stand.

Tolerances:

All dimensions are easily modified in the SCAD file.  Even if you have the same stand model as I, I doubt their manufacturing tolerances are perfectly consistent.  I recommend printing a small 1/2" section and then adjusting the ID and OD until you have a fit you like.  As rendered it fits my jack base tube a little snug (to stay in place w/o glue) and a touch looser on the extension bar (to move smoothly).  The snugger the fit the less wobble you will have.

I printed in PETG for durability.  However, this is not a load bearing part (the original pin still handles that).  So any non-flexible filament should work.

Print setting are in the 3mf:

  • Perimeters: 5 (for a solid lip)

  • Seam position: Random (for more consistent fit)

WARNING: Jack Stands hold heavy things (duh).  You accept all responsibility for your own actions.
