Christmas Cracker Gift Box

This is a christmas cracker gift box I designed to hold an egift voucher printed on an A4 sheet of paper. 

It is made up of two of the exact same part that snap together in the middle. 

It is designed to print vertically and some support is needed from the build plate only. 

I designed this to print on a Bambu Lab X1C with quite tight tolerances. I have included a test piece of the interlocking part that can be printed to test the fit on other printers. 

I did all my test prints in black PLA to fine tune the fit. When I printed the final version in a generic brand of Rainbow Silk PLA the fit was a little tighter for some reason, but it still works.
