Shelf split sleeve 3/4 inch

A shelf split sleeve for rack shelves that have 3/4 inch diameter poles. I don't know why you would want to print this as you can buy replacement parts cheaply. Also, you need to have tuned your machine very well in order to print this and have it actually work. Even then, it doesn't work as well as the ones that you can buy.

Might be used to convince your partner that the 3d printer is worth it.
