Sliding Keyboard Tray!

I bought a desk without a sliding keyboard tray, and didn't realize how much I wanted one. After searching online for one, none of them really seemed like they were worth the money, and since I recently upgraded to a new printer, I figured it was a good challenge to see what I could make.

The bulk of the credit here goes to EasilyBuild for his "Airsfot Ball Bearing Drawer Slide" design. All I did to it was extend the slide by ~30% to get just a little more extension out of it while still being printable on a 220 x 220 mm bed.

For this project you will need:

- 24 6 mm airsoft BBs (I recommend eBay, you can get small bags of 100 for about $4)
- 8 #6 countersunk wood screws (for attaching to the desk. The length you need will vary depending on how thick your desk is, I used 1/2" long screws for my 19/32" thick desk)
- 8 #6 countersunk wood screws (for attaching the tray to the bearing slides. You can technically use any length screw here but I just used the same 1/2" long wood
