Rock Wool Square Net Cup
thingiverse
A net cup designed specifically to fit rock wool. Dimensions of the cup itself are 1.3 x 1.3 x 1.45 plus the brim to suspend the cup over the liquid. I printed upside down and with supports. Just remove the supports and the four pillars in the corners which are basically just used as extra support. Printed using 0.4 nozzle and 0.2 layer height. I got tired of using circular net cups with a square rock wool cube, so I made this.
