@bear_lab @foosel pressed the pulp in place with my fingers. At the moment testing sand at the inside with and without a plastic bag as a seperator. Sand was a spontainious idea - looking not to bad actually. 😁
Definitely something in the inside is needed because of warping, but its difficult because its very fragile at the beginning.
I think it will be a lot of work and further experiments needed.
I'll share my experiences with the different methods. :blobcatderpy:

What do you think of #papergryd as a name for my cardboard recycled #gridfinity bins?
