Summary

I remixed these from Mattysek's IKEA Lack Enclosure Creality Ender 3 - cylinders.

Half of them have been re-deisgned to fit a #6 (US) pan head wood/sheet metal screw. The other half have been sized and threaded to fit an Ikea Lack leg screw. They are 29mm in diameter so they should fit the risers holes.

I also included 10mm/9mm cylinders that fit both screw types for the 10mm risers (not the 70/100mm risers.) The 10mm cylinders fit flush with the top of the riser. I also included the 9mm cylinders so that they wouldn't interfere with the leg placement in the riser in the off chance that the 10mm cylinder is taller than the riser.

Placement:

-The ones that have "lack screw" on their label screw into the holes on the bottom of the Lack table. I recommend screwing the screw into the cylinder first before threading it into the table.

-The ones that have (#6) in their label are the ones that screw onto the top of the table. For hole placement I measured the distance of the center of the holes on the bottom from the corners (for me it was ~1 1/16" from both sides,) and using said distance as the place I drilled the holes with the smallest drill bit I had (1/8" or so.) I used 1 1/2" long #6 pan head wood screws to screw the large ones down, but I'd recommend using a shorter length screw for the 10mm cylinders.
