.75" Rockwool mini-cube netcup

<p>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.</p><p>Also included is a spacer to fit these where a 2" netcup would fit</p><p>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!</p><p>I like natural PLA/PETG for anything in contact with the roots, since it's safe for food and no dies other filaments probably aren't a problem though, there's also FDA food safe filaments, but that's overkill IMO for indirect contact like this</p><p>for the spacer, any filament works, dark colors are preferred for light blocking</p><p><br>Fair Warning: the long version seemed to get a bit sloppy with how tall the walls were and might lead to failed prints, I recommend the stouter cube version which prints great.</p><p>Print Stats:&nbsp;</p><p>Adaptor: ~12m, 2.42g of filament($0.04)&nbsp;</p><p>Cube Netcup: ~20m, 1.97g of filament($0.03)</p><p>For the Wide-mouth Mason jar to 2" lid:<br><a href="https://www.prusaprinters.org/prints/60322-wide-mouth-kratky-jar-lid">https://www.prusaprinters.org/prints/60322-wide-mouth-kratky-jar-lid</a>&nbsp;</p>
