I had some really ovoid plastic eggs I wanted to print on and needed to lower my pen arm so the bottom of it was below the base of my egg-bot. I kind of wanted the whole thing higher anyway for better ergonomics.

These are included in the onshape design of my re-redrawn eggbot (included as a source here) if anyone wants to modify them.

Should work on any eggbot that uses this same spacing between the bottom rails.
