A small PCB tray for use on a desk or table, including built-in feet! The STL is sized for a 2x2 inch board with through-hole components.
Modifying the design
To modify the X-Y size of PCB, load the .FCStd file in FreeCAD in Part Design mode and change the base "Sketch". Add a small amount of slop to the nominal size of the PCB, such as 1mm. To change the height is a bit more complicated, you need to modify the formula for the "Length" of "Pad"; the first value (3.2 mm) is the available clearance. 3.2mm was good for me with a 1.6mm thick PCB that had through-hole components. Once you're done, export the "Body".
Removing the feet
If the feet aren't useful for you, just delete the last two steps, "cone" and "multitransform", or export "Pad002" instead of the whole "Body".
Printing the design
Unless using dissolvable support (which I didn't test), the printing orientation needs to be vertical with the tab at the top. Mine are printed in PLA; the tab needs to be able to flex when installing the board, so more brittle plastics are not a good choice, especially if it is printed vertically because the bending action is in the weakest direction.
