Quick-Deploy Projector Mount

This is a quick-deploy projector mount that works perfectly in an IKEA Kallax shelf or similar. A standard 608zz bearing in the center of the fixplate leads to smooth operation while the spring-loaded stopblock allows the arm to lock in at the top end of the rotation. The two guide-pins prevent over-rotation at both ends. This mechanism has been tested to around 5kg (11 lbs) of holding capacity without breaking (though the test was only for a short time).

At the end of the arm a hole is placed for a standard ¼"-20 camera screw to fix the projector to the arm. It is modelled for a 110x110mm projector like the Philips PicoPix I am using, where the screw-hole is centered. The hole is just over 6mm in diameter so that the screw is captive once it has been screwed in once. Therefore be careful on this first screwing to not crack the material. All parts are printed with more walls than standard to ensure greater strength.

If you need the arm to fold out in the other direction to what's shown in the photos and video, print the “mirrored” print profile where the arm, fixplate and stopblock have been flipped.

Assembly

The fixplate is mounted using double-sided tape (I recommend VHB-tape from 3M), on both the back and top sides. It is advisable to fix the tape to the fixplate first and then clamp it down for a bit to ensure a strong bond. Make sure to not place tape over the hole cutout for the stopblock

The spring has to be inserted into the stopblock from the back and both need to be inserted into the fixplate before it is glued to the wall. The exact spring necessary is has a 12mm diameter and is 30mm long. As this exact model is not available in Maker's supply, you need to buy the 12mm by 70mm spring and shorten it manually. When cutting the spring, make sure to wear eye protection and gloves in case the spring jumps somewhere after the cut is performed! I reccomend placing the cut end of the spring inside the guide on the stopblock so that the proper end of the spring can face against the wall.

For greater strength and printing ease the 3 pins (1x8mm and 2x6mm, each 15mm long) are printed horizontally and need to be press-fit (hammered, best use a rubber mallet) into place. The bearing is also press-fit into place in the fixplate. 

Notice on Remixes

If you wish to modify this design for another projector, I have included the Fusion 360 files in the raw model files. Please be aware though that uploading any remixes is not allowed under the exclusive model program license.

Notice for people who printed V1

If you previously printed Version 1 of this design which only relied on the interference in the guiderails to hold the projector up, please be advised that for me the pins started to wear out after a few weeks of use. Therefore the projector began to sag and was no longer level. You can print the “Fixplate V1 Addon for Stopblock” profile and mount this next to your original fixplate. The design is made to work with the original Arm.
