Velux Window Opener

prusaprinters

<p>I did this for a Velux roof window, which was hard to reach. Contrary to a simple hook this works perfectly for opening and closing the window. It might lack some printing optimization (e.g. for the holes or layer orientation) but it was a first shot and worked fine for 10 months now with daily use, until a friend just twisted it the wrong way. I reprinted the broomstick-part with a lengthwise layer orientation (see picture) to make it a bit sturdier but if you print it upright you don't even need supports.<br>When pushing it close, pay some attention to the angle and it should work just fine and become very easy very soon. It is a bit lose fitting to enable pushing directly against the printed part instead of just the screw, so you shouldn't worry about that too much.</p><p><strong>Shopping-List:</strong></p><p>(Allen) Screws:</p><ul><li>4x M4x30</li><li>4x M4 Nut</li><li>1x M5x50</li><li>1x M5 Nut (best would be a self securing nut, but it's not necessary)</li></ul><p>&nbsp;</p><ul><li>(Broom)stick (about 23 mm, fitting is more on the lose side if printed upright)</li><li>2x random woodscrew with different slot-types to make things a bit more tedious.</li></ul><p><strong>Printing:</strong><br>Doesn't really need supports.<br>Printed it with 30% gyroid-infill.<br>PLA and PETG both just work fine.</p>
