So I use my projector for DnD and watching videos. I wanted a quick and convenient way to change the angle from pointing down to pointing at the wall. So I come up with this, it can turn 360 degrees on one axis and 180 degrees on another axis.

You will need 2x of part1 1x of part2 1x of part 3 4x 7/16" or 12mm bolts and nuts 2x 1/4" or 5mm bolts and nuts 4x wood screws

I recommend printing this first then going to the hardware store and test fit the bolts in store.

I also used parts from this projector mount https://www.amazon.com/Mount-Projector-Universal-Projectors-MI-604/dp/B00YZ7N7WM/ref=sr_1_1_sspa?crid=3BBWSTHUZVU5I&keywords=projector+mount&qid=1574632380&sprefix=projector+mo%2Caps%2C176&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFVQ0dTVEVaTEoxWEUmZW5jcnlwdGVkSWQ9QTA0MDAwNTJRQjNLMFRDQU1TMk8mZW5jcnlwdGVkQWRJZD1BMDA4NzYyNDNKWFU0RUIxVkpGSkwmd2lkZ2V0TmFtZT1zcF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl
