Bushnell 1x-4x Quick Adjustment Throw lever

This was designed to be a tight fit, without the need for fasteners. I would recommend printing at a lower resolution first in order to test the fit of the lever, then scaling up or down. I used rafts because I got a bit of an elephant's foot on the base layer, but the need for one is probably not necessary on most printers.

Scale to 1000% in the slicer right off the bat.
