I got mine yesterday, and have the first one assembled (left). To the right is the 3D printed one that I modeled up last week.
One interesting comment -- I've only unwrapped one of them so far, but this one had 3 different colored LEDs included. There were 2 blue, 2 green and 2 red. I replaced them all with blue (because I like the look of blue -- I'm being merciful and setting my blasters to stun I guess), but definitely listen to the "check the colors of your LEDs" advice in the build guide and be prepared to swap some out.
I also had a hard time getting the brass tube to fit... not sure what I was doing wrong but it was about 1/8" too long. I trimmed it down rather than fussing about it too much.
LOL! Sorry not sorry...Like you, I've been waiting a long time for these and had been away...logged in last night and saw they were in a production run and jumped on em. Looks like they'll make more so no worries.
