Bits box containers

Very basic storage containers to fit inside a Makita Macpac1 box.
I had some small lengths of PLA left over from various rolls so thought this would be the ideal project to use them up.

There is 4 different size containers with one of them being nested.

UPDATE;
I've added the original designed boxes that are a little bit thicker with filleted internal corners, There's Small/Medium/Large in style A & style B.
The main reason I didn't use these for the final design was mainly due to print time & I believe the final models are strong enough when fitted together, & if/when they do break it's quick & cheap enough to replace with any left over filament ends.
