adjustable moldwall

First time sharing something so forgive me if I do anything wrong.

This is an adjustable moldwall I made in fusion 360. I use it for making silicone or urethane molds.
It needs a bit of sanding and lube to get the pieces to fit. I move it back and forth a few times to make it smoother.
Feel free to make changes or suggestions as this is a work in progress.
I added a hole for a bolt in the blocks in case they would move too freely but I found out they stay in position pretty well with just the rubber bands.
