In my continuing education of printing, I decided I wanted a bigger moss ledge and so I decided to learn to make one. biggest problem I found with moss ledges is getting the suction cups with the pilot holes.. but the dollar store as regular ones with a inset for metal hooks. 1 buck 6 cups.. so Solution make my own..

Forr aquariums you really should be using ether Pla or preferably Petg and before adding to your tank give it a good soak in warm water.. really warm if you wanna shape it a bit like around a cup or bottle and then let it rest in de-chlorinated water for a day or so just to make sure nothing is attached you don't want. take dealers choice of aquatic moss.. and tie down with thin fishing line or preferably cotton thread as it will biodegrade eventually as the moss grows..

If you want to print and sell that is fine. It is a learning project for me. no need to ask Print it, sell it, remix it,
