This is a Variable camera (or other things) mount for Ikea Platsa. The Freecad file is parametric, so you can customize it.
The recess in the holding arm is for a 1/4" screw (default camera gear thread), i used a 12,7mm long one with a printed washer (see Models).
You also need 3 M3 screws and nuts (the nuts used here have to be 6mm from flat side to flat side and 3m thick) and some washers depending on the length of your adjustment screw.
The Mounting screws are 4,5x16 wood screws with a sink head.
I have printed mine in PETG with a layerhight of 0.3 (the washer in 0.2) and a 0.4 Nozzle.
The author marked this model as their own original creation.
