Bushnell 1x-4x Quick Adjustment Throw lever

I would recommend printing at a higher resolution first to ensure a snug fit without the need for fasteners. It's best to test the lever's fit by scaling up or down after printing at a lower resolution initially. Relying on rafts may not be necessary on most printers, but I used them to avoid an elephant's foot on the base layer. Scale everything in the slicer right away to 1000%.
