This is a 3d printed switch tester that I made. To make it yourself, go to keyboard layout editor and select the amount of keys that you want. Next, import the raw data into skillkb and add padding as you see fit. Next, upload the dxf file that skillkb will give you into your 3d modeler of choice and extrude 1.4-5 mm. You will also need to add some feet so that the bottom of the pins don't touch the ground.

Happy printing!
