Lack Third Table Brackets

These are additional brackets for securely adding a third (or fourth) IKEA LACK table to your [lack stack enclosure](https://www.thingiverse.com/thing:2864118). I printed these out of PETG as that was what I had laying around, but other materials should work just as well.

I came up with these as I have cats and was worried about them knocking the tables over, or even just a bad bump knocking the tables down.

Having a third table improves the height that your printer is at, in addition to providing more storage space for filament spools, tools, and so on. Adding a good 20-30 lbs on the bottom table also helps stabilize the lack stack and reducing wobbling.

The holes are countersunk for a basic #8 wood screw. I used Hillman #128005, which is a #8x1" hardened zinc screw, but again it was what I had around.
