IKEA PS Endcaps

I put 2 of my [IKEA PS](https://www.ikea.com/de/de/p/ikea-ps-schrank-weiss-10251451/) cabinets on top of each other. To do this, I sawed off the legs of the top cabinet. Because I had done [another project with the cabinet](https://www.thingiverse.com/thing:5524201) some time ago, I had of course wasted the end caps and needed new ones quickly. So I just designed a few replacement caps. Maybe someone else can use them, they fit all square tubes with an inner diameter of 17.5 mm and an outer diameter of 20 mm.
