My version of the modular silicone mould containers, made from plastic to be easier to demould silicone from.

5 x 5cm blocks to allow customised mould sizing. Can use for plaster, but harder to demould.

Use bullclips to seal the pieces together, along the ribs.

Higher quality is better so the layer lines don't show up and can be demoulded easier. Probably best to give it a sand and prime.

Use demoulding spray or petroleum jelly on the walls before pouring silicone so demoulding is easier.
