Projector bracket to project on the ceiling

This project idea was born because of a lack of space for a real monitor and PC working-space. My original working-area was occupied by my wife. The remainder of the flat does not really allow for an extensive desk and I recently purchased a projector to replace the TV because my Kids decided to test its sturdiness with a hard-plastic ball.

Now I really prefer laying on the couch for working in a relaxed position thus preventing the typical "geek"-rounding of the back - though blindly typing skills on your keyboard are mandatory.

I have a Kolink Rocket to take up minimum space and found the aluminum outer wall perfectly fits for a hook which prevents the projector from falling over.

I build this in Fusion 360 and Printed on an Ender 3. If you have a bigger printing-bed and want to place the mount directly onto the ground instead of attaching it to a Kolink Rocket I recommend extending the legs due to stability-issues when not combined in such a way. In any case you will need 90°-Connectors for HDMI and power connection to the Projector. Also make sure the projector is capable of projecting upwards which is usually not the case for every projector. With the upcoming technology of LED Projection this is feasible though and marketed i.E. by Acer as a feature. Also I'd advise you to take the distance of your ceiling, resulting screen size and the projector-angle into account so the screen is projected as close as possible to your viewing center.

Notes:

For printing the threads look for Slicing tolerance settings in your slicer to be exclusive making the threads easier to fit. You still might have to screw the threads multiple times until everything runs smoothly. For Cura: --> Print Settings --> Slicing Tolerance --> exclusive
