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" hole to mount it on a arca-swiss plate and one with a Arca-Swiss Base but the Arca-Swiss Base is much more stable. You can mount it directly on a normal tripod with Arca-Swiss.
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
