Cover for Chess Set by Pork3D.com

I saw another use upload a make of the Chess Set by Pork3D.com and really liked their cover, but when requested by another user they never provided their STL. So I designed my own, with my next to 0 modeling skills (This is actually my first model). The cover is held in place by four posts, the same size as the pieces. When clicked into place, they hold tight enough that you can dangle the game by the lid. I printed my chess set at 115% scale, so this was originally designed for that scale, but I scaled it down to appropriately print at 100% scale. Please let me know if the scale is wrong so I can fix it. Enjoy!
