3-Axis CNC Mill Project

[Robin Hewitt]

You could turn the open frame into a cupboard to keep your knick-knacks and controller in. If you cut Melamine faced board to a good fit on 3 sides it would make that base totally rigid.

Beware the temptation to make the gantry tall for that large lump you think you might want to cut some nebulous time in the future. Height costs you rigidity.

Your tool is unlikely to extend much more than an inch from the collet so you'd only be scratching the top of that lump anyway.
