easy corner feet

I needed to raise some objects a few centimeters off the floor and came up with this project.Print four of these, grab a board of any material that's 1.9 cm thick, and you're done.The shelf can simply rest on top of the four feet with no need to fasten them together.You can print them in PLA, and with 25% infill they are plenty strong (I tested up to 25KG), but if you need to support more weight, increase the infill and wall loops. External dimensions:Base diameter: 60 mmTotal height: 125 mmInternal dimensions:Internal diameter: 33 mmRecess depth (short side): 42 mmRecess depth (long side): 44 mmUseful heights:Height from the ground of the inserted shelf: 103 mm
