BK1s BK2s Magazine short 10 dart (12 dart max)

I wasn't sure about cutting up my BK shell for a talon mod, so designed a magazine.

I have an Bambu a1 mini so this mag is the limit of print bed size, it uses a talon spring so easy to get hold of. 

I've made multiple revisions and tweaks to made sure it feeds correctly as the BK's are sensitive to slow feeding. at the very maximum it can hold 12 darts but the spring is very compressed so I would advise 10 or 11 darts.

Print guide.
printed with 0.2 height, 2 or 3 wall, infill 15-20%

Build Guide.
1 spray on some lube onto both halves.
2 fit the halves together, push them together evenly. (glue the halves together once its been tested working) 
3 slide in the follower (make sure its the right way around) (the spring can be screwed to the follower)
4 slide in the spring 
5 compress the spring and put in the spring holder
6 slide on the bottom cap
make sure the spring holder fits into the bottom cap

The spring tension keeps it all together. the follower can push past its stops at the top of the magazine.
Test the mag with shorter darts (36mm) if its all working correctly and feeding ok then glue the halves together.
 

I could make a longer magazine but can't test it. comment on lengths and i'll make them and upload the files
