I needed a handle to move my IKEA RÅSKOG trolley which I use for scale modeling equipment and to which I have attached a side panel (see: https://www.printables.com/it/model/353304-raskog-side-panel-connector).
The thickness of my panel is about 10mm and the stl file has the right dimensions. However, I have included both the step file and the fusion 360 file. In the latter, among the custom parameters, the dimensions of the panel thickness (panel_tichkness) and the overall thickness of the handle (handle_tichkness) can be specified.
Printing done by turning the handle to one side. PLA, nozzle 0.4, layer height 0.32, infill 20%. Supports enabled.
The connection with the panel can be made with two M4 screws and relative nuts. It is obviously necessary to drill the panel in correspondence with the screw holes.
The print displayed in the photo has the writing that has been deleted in the attached files.
