Halot One vat cover

Print in place hinged vat cover, printable on the Halot One itself.

I've included cxdlp so you don't need to slice it again... just load the cxdlp straight onto the printer. This is 5% oversize in all dimensions, because my first print shrunk by that much. If you're not getting that much shrinkage, you may want to scale it down a bit.

I did need to cut the screw slots deeper... just ground them away against a drill bit in a drill press. Some-one may want to modify the design for that. Or I may do... it's currently a bit fiddly getting it into place.
