Summary

Skirt or foot for hiding the hole in the floor, where the pipes (or tubes in my case) come out of the floor and go to the radiator.

Instructions

Printed succesfully on Prusa MK3s, with Prusament ABS.
Settings:

Layer height: 0,20mm (speed)
100% infill
"support from bed only" was enabled
Brim enabled
Bed temperature raised to 110 degrees celcious for the first layer, and 115 deg. celcious for other layers, to avoid the parts warping.

Takes a little less than 3 hours to print.

You need two of the RadiatorFoot-New.stl, and four of the RadiatorFootCylinder-New.stl to print a complete set. I used a stanley knife and plyers to remove the brim and support.
