<h3><strong>Polar Wedge with linear gearbox</strong></h3><p>This is a little but solid polar wedge for astrophotography.</p><p>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.</p><p>The PolarWedge can rotate about +/- 60°</p><p>The Setup, you can see on the photos, weight is 4292 gramms and it is not a problem for the PolarWedge.</p><p>You can print all parts without supports.</p><p>&nbsp;</p><h5>Hint:</h5><p>Print the Rack on the side and the knob on the small diameter, it works!</p><p>&nbsp;</p><h4>Parts, you need to assemble:</h4><ul><li>1x M8x45mm Hex Screw VA</li><li>1x Locking lever M8</li><li>1x M4x60mm Threaded Rod VA</li><li>1x M4 Hex Nut VA</li><li>1x M4 Hex Nut witch cap VA</li><li>1-2x 1/4" Nut VA - one for the wedge, ode for the base without Arca-Swiss.</li><li>1x M4 Insert max. 10mm long for the Rack</li><li>1 drop of superglue for a nut on the M4 threaded rod</li><li>1 drop of Loctite 243 for the nut with cap in the knob</li></ul><p>&nbsp;</p><h5>In the pictures you can see a complete setup with:</h5><p><strong>StarTracker:</strong> <a href="https://www.thingiverse.com/thing:4889007">https://www.thingiverse.com/thing:4889007</a></p><p><strong>The tracker has tuning parts:</strong> <a href="https://www.printables.com/de/model/184153-tuning-parts-with-bearings-for-heavy-duty-planetar">https://www.printables.com/de/model/184153-tuning-parts-with-bearings-for-heavy-duty-planetar</a></p><p><strong>L-Mount:</strong> <a href="https://www.printables.com/de/model/184152-l-mount-for-heavy-duty-planetary-astro-tracker">https://www.printables.com/de/model/184152-l-mount-for-heavy-duty-planetary-astro-tracker</a></p><p><strong>Caps for Polarscope:</strong> <a href="https://www.printables.com/de/model/184149-caps-and-tool-for-polarscope">https://www.printables.com/de/model/184149-caps-and-tool-for-polarscope</a></p><p><strong>Notes:</strong></p><p>No Supports needed, print it with 100% infill for maximum stability.<br>I printed it with Carbon PETG</p><p>&nbsp;</p>
