Summary

This is my latest version of Moss Planter - 5.5mm space inside when fully closed and you can now put sand of 2-3mm size as weights. Print without supports, print as economical as possible. I've used ABS as usual and got a chance with green color. Get some C type suction cups or whatever you called it and attach it on your tank walls. Originally it was designed for my Fissidens fontanus propagation but later used as well in Riccia fluitans, Plagiomnium affine, Hydrocotyle tripartita JP, and one shown Micranthemum tweediei. They should be snug-fit after print or just apply super glue if needed. Enjoy.
