Linear Gearbox Polar Wedge

Polar Wedge with linear gearbox

This is a little but solid polar wedge for astrophotography.
I designed 2 versions of the Base, one with a 1/4" mount and one with a Arca-Swiss Base but the Arca-Swiss Base is much more stable.
The PolarWedge can rotate about 60°
The Setup, you can see on the photos, weight is 4292 gramms and it is not a problem for the PolarWedge.
You can print all parts without supports.

Hint:
Print the Rack on the side and the knob on the small diameter, it works!

Parts, you need to assemble:

1x M8x45mm Hex Screw VA
1x Locking lever M8
1x M4x60mm Threaded Rod VA
1x M4 Hex Nut VA
1x M4 Hex Nut witch cap VA
1-2x 1/4" Nut VA - one for the wedge, ode for the base without Arca-Swiss.
1x M4 Insert max. 10mm long for the Rack
1 drop of superglue for a nut on the M4 threaded rod
1 drop of Loctite 243 for the nut with cap in the knob
