These are printable feet for the SK-Tank. They protect your tabletop from the sharp edges of the steel frame, and are designed not to interfere with the bolts holding the frame together. The front feet can be bolted to the frame (this wasn't practical at the back), and the feet have holes to bolt them down to the tabletop, although if you really want a solid connection that tightly couples the Tank to a heavy concrete slab or something, you may want to use steel angle brackets instead. These will at least keep the Tank from moving around.
The models don't require any support or brim. I would recommend 25%+ infill though. The front foot model is for the front left corner, and should be mirrored in the X direction for the right side. Holes will print a bit small so they can be drilled out to 5mm.
If you want to bolt it down, holes should be in a rectangle, center-to-center 530 mm across (X) by 441 mm front to back (Y) as measured on my printer.
Enjoy!
