Chain Store Print in Place - In xích liền khối, nắp cứng hơn

The genius of this puzzle is its simplicity. Thank you for making this!

You can print the chain in place which I think is a little more graceful way to do it. Anything that avoids the use of superglue has to be an improvement. This chain will not break.

You'll of course need to use a brim to print the chain, but it is easily removed after printing. Supports are not necessary. Print .20mm with 15% infill.

I slightly beefed up the end of the lid. It broke it for me immediately when trying to force it on; this fixes that.

Lastly, the box was almost too short for the chain to fit, so I vertically extended it exactly 1mm.
