Ill only be able to make items less than 300x300 but will be good for testing. thanks for the advice.

I have the same nuts. I drilled out a chunk of mdf the diameter as the nut, slit it on one side, drilled through and used a couple of M5 bolts and M5 teenuts (captive recessed nut) to put the 'squeeze' on the delrin. 4 mounting holes in the corners allows ot to be bolted to the underside of the table/gantry/etc.
