Throw lever for a rifle scope. It makes zooming IN/OUT much easier (even in gloves) :)

Uploaded model (both versions) has these parameters:

• inner diameter: 46,0 mm

I use this throw lever on my rifle scope Vector Optics Matiz 3-9x/50mm but it can be used for any other.

If you need to adjust the size, just use scaling in Prusa Slicer (or others). No more modifications are required, please check below:

Scaling for your scope diameter:

How to scale properly? Here is a simple example:

• inner diameter: 46,0 mm (provided model)
• inner diameter required: 42,0 mm (your scope)
• scaling factor: 42,0/46,0 = 0,9130 * 100 % = 91,30 %
• scale only X and Y axis, not the Z axis!

Printing:

• PLA or PETG (preferred)
• 3+ perimeters
• infill 20-30%
• avoid crossing perimeters
• no supports

Requires 1 piece of M3x10MM long allen screw and 1 piece of M3x5MM ODx3mm long brass nut.
