Velux Automation

thingiverse

Attempting to build add on automation for my Velux skylight. Requires a NEAM 17 Stepper Motor. I've tested this with my extruder motor which is a Kaysanhttp://www.kysanelectronics.com/Products/Detail.php?recordID=7850 Posting the STL files here, the scad files can be found on github. https://github.com/krbaker/3dprinting/tree/master/velux-automation Instructions print one of each part. Also requires an 8mm allen wrench for the drive. Put the small gear on the NEMA stepper and use a 3mm set screw to keep it in place. You'll have to guess exactly where on the shaft it goes, mine is just about flush with the end. Put the top onto the mount and use 4 x 3mm screws to hold it together. leave the screws just flush with the top. Put the NEMA 17 stepper face down onto the top mount plate so the gear sticks through the hole. put the screws from the velux crank through the two mounting holes, put the spacer on that. Check the orientation of the ridges in the skylight, make the spacer plate match, add the space to the stack. put the screws all the way through the mount and the spacer. Put the big gear into the slot. Push the 8mm Allen key through the hole in the top plate, gear and then mounting plate. Screw the mounting plate onto the skylight using a screwdriver going through the top plate and gear. You'll have to rotate the gear to access the screws. Also note you might want to open the window to a mid position so that you have freedom to move the gear in both directions. I'm sure this voids your warranty. I can't take any responsibility for damage you do to your window or anything else for that matter.
