Sturdy Carpet Riser Foot (for Computers, Tables, Power Supplies, etc.)

This is a sturdy riser foot meant to keep things elevated off of carpet. I use them for keeping a computer and UPS off the ground for air flow, and have also used them for stacking boxes off the ground in my garage. 

The foot itself is pretty strong.. I believe a single foot printed in PLA can handle over 100 pounds (YMMV.. I made the things a while ago and don't recall the exact point of failure.. Its quite a bit though :P)

I suggest printing at 0.3mm layer height with at least 3 walls, 4 top layers, 3 bottom layers, random seams, and ironing enabled. 

These are designed in a way that saves material and requires NO infill. The feet are hollow with the exception of some small columns placed inside the void. The columns help to support the top layers in printing, help (to a lesser degree) distribute load on the foot, and finally serve as a warning that the load is starting to deform the foot by crumbling inside the cavity. Once the supports crumble they will rattle around inside the void to indicate that the structure may have started to deform and may not be suitable for reuse with heavy loads.  

I have provided the STL for the actual foot, as well as a 3MF with 4x feet laid out. They print flat but I highly suggest painting snug supports on the entire bottom. In the 3MF you will see a small strip going through the middle. This makes removing the small snug supports pretty easy as the strip and all of the supports should peel off of the bottom in 1-ish piece. Actually paint the supports vs toggling automatic supports since the auto supports will also fill the void in an effort to support the top layer (you can check “supports only on build plate” if your slicer has the setting to prevent this.) You can also manipulate the auto supports to add additional structural integrity if you want :)
