To make a Vacuum Formbox I needed a connection to connect the vacuum cleaner to the box. Since Dyson is a world standard, I have decided to use the Dyson connection for this, you can easily get it all over the world.
The size of the hole for the wood (or other material) is 50mm This is a standard size for saw drills, which is easily available at the construction stores.
Doesn't matter PLA will do, I used NGEN
Make sure to use support.
Clean the print, mark the holes and pre-drill them in the formbox, then screw the vacuum connector to your box
