Ok looking at other sources than pipe makers now. So far here is what madvapes offers
Gripper 510 Extension << Looks to be long enough tho it is currently out of stock $3.99 ea
510 Battery Extension << You may be able to thread together 2-3 of these for the right length $1.99 ea (though it may add some extra resistance before hitting your carto, you may wanna ask how it will affect performance fom someone more experienced than I)
More incoming...
Gripper Mod 510 Adapter... Same Gripper Extension, 1 in stock $5.99 ea, you may wanna measure your broken one to see if length matches, these are 47mm long
That's the one I bought. It's about 6mm too long. I need one measuring 41mm (I measured, lol). My issue with adding resistance is that it's a straight 3.7v device.
