ONEUP EDC Pump dual CO2 adapter

thingiverse

This is an adapter ring to allow for storing a second 20g CO2 canister inside the One-Up components EDC pump. This threads onto the neck of the second canister and keeps it from rattling against the one attached to the cap. I put a circle of self adhesive craft foam on top of the adapter as well as a small circle of regular craft foam at the bottom of the pump bore both to further prevent rattles. The threads are a snug fit allowing for some room to adjust depending on the brand of canisters. This is for the large,100cc pump. It may work with the small,70cc pump and 2 shorter 16g canisters but I don't have one to confirm.
