Fits perfectly the Keter Sigma series shelves. Bough 4 sets and didn't want the 5th shelf so I made a 5th set of shelves, but was missing the caps.
These aren't the most optimized thinness wise and in general a very amateur model made in Meshmixer - but hey, they work! Fit quite nicely! Had to iterate a few times to get a snug fit.
NOTE: Printed using 0.8 nozzle for speed (nearly quadruples the speed!).
