CNC-router cut table made from 15mm MDF or plywood.
The dimensions are 780x780mm, and 595mm high.
It will hold together just under the force of gravity, but you can screw it together using 8x 25mm screws, if you want more security.
It has been designed to fit on one half of a standard 2400x1200 sheet. (4'x8')
Cut using your CNC router and a 6mm bit.
Dogbones are already added for interior angles.
Use a 1/4" roundover bit to soften the edges.
Finish in anything you like, wax, varnish, oil, paint...
