This is a very simple piece but very useful if you happen to do resin or plaster molds.

Been looking for a simple solution for making mold boxes on the fly. Foam core works great but can be a bit pricey and is usually destroyed in the demolding process.

I saw some plexiglass adjustable forms online that looked great but they go for $40 bucks! So I can up with these 3D printable forms that do the same thing.

They cost under $3 buck to print and you can use them again and again.

Print out at 100% or scale up and down according to your needs.

I printed several out by scaling just the horizontal axis up/down to get different heights for larger/small casts.

Anyway enjoy.
