Velux Window Opener

thingiverse

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 direction. 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. 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. **Shopping-List:** (Allen) Screws: * 4x M4x30 * 4x M4 Nut * 1x M5x50 * 1x M5 Nut (best would be a self securing nut, but it's not necessary) * (Broom)stick (about 23 mm, fitting is more on the lose side if printed upright) * 2x random woodscrew with different slot-types to make things a bit more tedious. **Printing:** Doesn't really need supports. Printed it with 30% gyroid-infill. PLA and PETG both just work fine.
