The original level holders worked really well, however, I needed longer arms for it to properly level a 40 oz tumbler. I traced the original model and added a number of features to it.
Changes:
Added longer legs on one side
Extended length to accommodate larger items.
Added square recesses to both ends so they can be mixed and matched or swapped to smaller sizes if needed.
UPDATE 17-JUL-2026: Added picture to show the different orientations.
