These are reusable wadding for firing 6mm BBs from breech loading paintball guns like the Umarex T4E HDS68. I've found that a mix of steal and paintball 6mm BBs works best.

Print: 1 Base 2 Sides 2 Cap .5 (Optional)

Connect the two sides to the base. It has ~6mm hole at the top for loading BBs. Optionally add a cap. The completed shell should be then stable enough to hold, but still separate as it leaves the barrel.

I have a few experiential caps:

• Deconstruction is angled inwards to promote pushing the two halves apart when fired.
• Spinning should open up the shot by having the wadding spin.

I've not tested these enough to know if this actually works.

Notes:

• These are very tight in the barrel. It needs a bit of force to load.
• Even with the 12ft lb model the individual pellets are quite weak.
