556/300 10/15rd clip 100/150rd case + speedloader

This combines the best features I saw from other designs. Inspired by many, but the CAD is original.

• Latch closure
• Large capacity (100rd and 150rd)
• Compact clip-based storage
• Included speedloader designed to work with the clips, with magazine retention so you don't need to hold it in place

I highly recommend the Supertack/cryogrip plate for the clips. If you use high adhesion plates, you can remove the brims on all objects. Otherwise, the clips are especially sensitive to poor bed adhesion, and you should only print a few clips at a time or else you risk wasting a lot of filament.

UPDATE:

- Added 15rd print profiles (150rd case and 15rd clips)

- Modified lid geometry to reduce wiggle when closed

- Modified speedloader to add magazine retention with a lever. No more need to hold the magazine in place.
