/diy/ - Do It Yourself

I need to mount a projector 2 meters above a table looking down. The mounting has to be made in a way that it can be taken apart because it's for a live video mapping showcase for college and I can't use any ceiling or wall mount. The projector itself weights about 5-7 kilograms.

I thought of making something like this (image below). I have 3D printers so I can make the joints and table grips out of PETG for a solid structure, but I don't know what to do about the actual rods of the structure. Any material that bends will probably flip the table easily if someone bumps it accidentally and any heavy material will make the build collapse or possibly fail after some time. I'm open to any kind of suggestions and comments, but please if you're gonna tell me it's not possible I would really appreciate some other solution or even a reason why my idea doesn't work. Thanks!
