7in Round Puzzle Frame

I made this specifically for a 7in wooden puzzle. Should work with a normal puzzle as well. Cannot use this for pictures. I designed the frame to mount to the picture hanging nails that I have (seen in pictures). If you are using something else you will need to modify the frame model. 

I used 

• five (5) M3 x H4 heat set inserts 
• five (5) M3 x 6 button head bolts
• one (1) small head picture hanging nail
