Remixed my old car vent model. Holds our heavy and bulky phones in place very nicely. Phone can be put in horizontal position no problem, most likely can be used with smaller tablets. It goes into your cdslot very snugly, please be very careful not do damage anything.

Working on a building site, high up under the ceiling i was lacking container to put in small screws, drill bits, etc. You dont really want to move around a lot and wiggle on heights. So i came up with this very simple idea. It was tested in heavy environment for couple of weeks (my print profile) and they hold suprisingly strong. With small lip on the outside it kind of clips onto the rail and can stand a lot of weight.
