I printed out the part today using PET on a DaVinci JR 1.0 printer and so far it looks promising. It remains to be seen how well it will hold up the to heat of launch....but if it proves to be only useful once per flight, it's at least cheap and quick to make (takes a little hover half an hour to print). I made 3 units for now. Hopefully can test one tonight.

Please let me know how it works out, I had one printed out from thingaverse when they have vendors linked, and it doesn’t fit.
The 2018 Catalog has the Skytwister which is the last regular kit that uses the retainer, although rockets in some current launch sets still use that. |
