Hi! do you know where I can get the end cap or plug model for a JT Outkast? It's the one that close the marker behind. Thanks!

how did u attach the air tank?

In the pic of of the stock setup, the constant air adapter is bolted into the part plug1.stl by pressing that part into the bottom of the ER2 co2 cap that screws into the bottom of the marker grip. The pictured co2 cartridge changer that is screwed into the attached constant air adapter isn't that heavy and the rig can support the weight. An air tank of any size would be too much weight for that one bolt, so I have a coiled remote quick change attached for open class pump games.

so if I were to want to make my er2 constant air instead of using air cartridges I would get a constant air adapter and what would I do with the end of the hose. Also what model did u use for the barrel?

The secret ingredient to the air mod is actually a standard threaded tube used in most Printer heat blocks. I linked the part in our ER2 mod group https://www.thingiverse.com/groups/jt-er2/forums/general/topic:32282 . I tapped the inside of a standard air fitting to accept the threaded tube, used Teflon tape and incorporated the existing white o-ring to make the seal. https://imgur.com/UM3JWw9
The barrel is just an old Phantom All American with green tape for a compression fitting, which performed way better than I expected. I folded just a bit of green tape over the end of the barrel edge and 1/2 inch into the barrel for a weird hacky ball detent, but it too worked very well.

Gosh Darn thanks

Taking a cheaper marker and decking it out like that is pretty cool. GJ

Thanks, it was pretty fun to play some speedball with and a couple of dives into the dirt actually broke the marker's plastic housing and not any of my printed PLA parts. Got a 1 to 1 bunkered elimination on a fully equipped tourney player and when I apologized for where my shot hit him, chestnuts, he said it didn't even bother him because I had done it with that crazy pump. lol
