Is that an aluminum plate on top? It looks like acrylic.

A must have for any Makerbot owner.

This works great! I find my platform moves a bit after several heat/cooldown cycles. This makes it pretty easy to level the platform. I really enjoy printing things for my printer... on my printer.

I'll second the note from PrettySmallThings to wait until they are completely cool before popping them off the platform. They will bend if you try to pry them off hot, and that bend quickly becomes permanent as they cool off the rest of the way. I pressed the nuts in with channel lock pliers.

This is great. Any chance you can make put them all on one plate for printing?

thanks for your great solution!

I did the same thing. Be sure to let the plastic fully cool before you pop your thumbscrews off your build platform - warped thumb screws are pretty useless.

Print these thumb wheels in ABS not PLA. I learned the hard way.

This is basically what I ended up with. I printed the four other pieces, realized that they were all messy prints, had tons of issues, and ultimately weren't needed.. so I dropped them for just these thumbscrews. I am only using 8 because I have a 6mm aluminum HBP and also a 6mm aluminum plate under that that my ball-bearing x-axis screws into. Works amazingly well. The bottom plate does get a bit of heat from the screws, but its nowhere near enough to melt the plastic thumbscrews.

They don't melt?
