I got the best measurements I could off of my blaster, it's just a tricky area to pull measurements off of. Assuming there's interest in this part (the number of likes on that post is not encouraging
) we'll need to just test and iterate.
In other words, go ahead.
(To be clear: I have a blaster already and have been taking measurements off of it. Unfortunately I glued some interior parts together before I realized how many upgrades I could make, so I'm waiting on a second blaster before I start the tail piece. Which is really the second-most important part after the nozzle, imo.)
