MDF is heavy for vibration dampening, it is cheap, it glues well with Elmers and it's straight and flat. MDF is just a finer grade of particleboard. There is a reason that this product is a staple in the residential cabinet industry. It is the best economical material for the job.
Well got the two bases together. Had to add bottom corner braces to one as it did not have any. Put the units together with wood screws on the frame and a spacer and screws in the back. Screwed up the frame screws as they were drywall screws and did not really grab well. The back screws were the fancy torx driven screws, which worked very well and I prefer them over the phillips going forward. For the top I had an old 3x3 coffee table top. I simply trimmed it to 26" long and that is done. Top still needs attaching.

Looks like it's actively wiggling in that first picture. :p
Office cabs, perfect for machine base.[emoji106]
If hidden fasteners not an issue, screw down thru top into face frames(4, 2ea) at front and cleat(2?2) you add at back(4, 2ea).
Countersink top and predrill hardwood face frames to avoid splitting. Should be plenty stout and rigid.
Its done. Ain't it purdy? Room for everything. Now I just need a printer cover and a few more items. (I have learned that 3d printers are never really done....)
