Its a warmholding plate that you can lasercut yourself. Its for holding things warm. (sorry but I dont know the correct english words). Its just a test, so if things dont match, please tell me asap. The jpg file containing the cut-out will be online soon.
You need sheetmetal 1mm, a lasercutter and a bending machine (if you dont want to bend it by hand). Just cut the pieces out, and bend it according to the 3d file. (you should bend it like this --> |L)
It uses tealights size 40x15mm. If you want you can add your own logo on it.
