.75" Rockwool mini-cube netcup
thingiverse
seemed silly trying to cram a square peg into a round hole, also the 1.5" rockwool cubes seemed way overkill for my little kratky plants, so I came up with these netcups to fit a 1/4 and 1/8th of a 1.5" rockwool cube which I found cuts up easily with a pocketknife. Also included is a spacer to fit these where a 2" netcup would fit since the rockwool is a nice cube, you can leave the netcup gaps nice and open, which should let the roots thrive! Also designed to print without supports, optimized for bridging!
