Eccentric Nut

This is a set of Eccentric nuts that are commonly found for your standard 3d printer.
One is using an 8mm spacer, 10mm total length, and the other is a 6mm spacer, 8mm total length.
They use a 10mm wrench, possess a 5mm bore, and have a .7mm offset. They both have a notch showing the direction of the offset bore.
In essence, they're the eccentric nuts you buy from your hardware supplier.
Use these for your 3d mockup, or print them for whatever reason you may desire.
