Attack 2: STACK THE LACK

NOTE: SAVE THE SPARE LEGS! If your following this build, you need them for LACK ATTACK #4.

Once I had a 4 Lack Stack with one Lack without Legs on the bottom as a base sitting in my living room I wanted a way to move it easily once it was complete. I knew it would need to move to clean/make room when company comes over (I like to print/work in the living room so I can watch the kids as well) so I also picked up a set of RILL casters at ikea (Article Number : 966.713.00) they were in the discount bin as the bag was ripped, $6, can't beat that...

I didn't see anything similar, so based on the Lack Stack adapter I knocked out a quick caster adapter for the bottom corners that would also serve as a corner protector for the legs as they tend to collect dings easily.

I built these to install 2 ways, I first used them with the posts which will press into the tables screw holes, this was intended to align them, see how they fit, and if they needed modification before I screwed them in place. It worked well for the first couple days and was surprisingly stable, but then one post broke so I screwed them down and into place. I'd skip the posts if I printed these again and go straight to #6x1" screws

As always, comments are greatly appreciated, in this case direction and pitfalls to watch for are also appreciated, If you've been here done this and have a better way please let me know.
