UPDATE:
The 54mm guides have been a long time coming, but they are available now. I have also re-designed the 38mm guides based on what I've learned making the 54s, and I have moved to a new, stronger material (PETG) which is also better in the heat of mid-day sun, inside a car, etc. The new 38mm guides will be available mid-October 2015, depending on this hurricane we have bearing down on us.
The launch reports from BALLS24 have been great!

AVAILABILITY: These are available from Animal Motor Works.
I've UPDATED the design a bit based on rockdoc's feedback, and I've posted a video. I think these are an improvement, although they take quite a bit more time to print. See post #60.
Some launcch video: in post #100
------------ ORIGINAL POST:
I'm starting this thread to solicit commentary from the group on some 3D-printed fly-away rail guides I've designed. I've mentioned them in other threads, and in the interest of not hijacking those any further I've decided to move the discussion here. This design is based on an R&D paper presented at NARAM-52 (2010) by Tim Van Milligan, so the basic concept is not mine, although the 3D-printed part was developed by me.
I want to thank atlcdp, who printed me a set of my original design, which unfortunately was not very good. The parts were fine, but my design was gawd-awful. I managed to get my hands on a 3D-printer for a little while, and so I've been able to iterate through several different concepts and improvements to get where I am now. There is about a pound and a half of dead PLA at the bottom of my workshop trashcan that represents a lot of mistakes.
Anyway, here is the original video I posted to nute's Redshift build thread. I have since updated the design a bit, and that will be detailed in post #3. The first guinea pig, er, lucky recipient of these things will be rockdoc, because he has a launch coming up this weekend. I have spent so much time playing with the 3D printer, I mean, uh, designing these things that I have neglected to even start my own 38mm rocket and will have some difficulty being ready for this month's MDRA launch. I have promised a few sets of these to some people and you'll be receiving those if rockdoc's experience is a good one.
Comments are welcome and appreciated.
