ERISAN Projector Roof Mount

Designed a cradle to fit my cheap projector and to go with the original mount. I printed it as it is oriented with dimensions of 162x108.5x156 mm. I found taking the rubber feet off of the projector during installation helped, as I left the tolerances low to give it a snug fit. I strung a rope around the whole thing (as pictured) to make sure it doesn't try to move side to side. It seems quite reliable.

Update: 5 months later and still going strong!
