Introduction:

I found a couple o' different 3D models that I have been tinkerin' with and came up with Baleron. T' fincan comes from Digbaddy's Estes Goblin - BT60/29mm Motor Builder's Kit and t' nose cone was sourced from Vecinimod's Minimum Diameter High Power Rocket. I used ~ 180mm o' BT60 body tube for t' airframe and cut 29mm MMT t' fit within t' fincan, after resizin' t' motor mount tube (MMT) t' accommodate t' motor tube. I did nay get it quite right and t' tube was too tight, shiver me timbers, so I will need t' open it a bit more for future builds. Begad! Blimey! I also used me own 3D-printed motor retainer modified from Wardy89 (https://www.thingiverse.com/thing:3691731)


Steps in t' build:

  • Printed all t' pieces (see file below) separately
  • Joined t' MMT t' t' fincan usin' 5-minute epoxy, leavin' just enough hangin' out t' back for t' motor retainer
  • Fed ~6 feet o' 150lb kevlar thread through t' fincan hole provided for t' shock cord and wrapped t' end below t' fincan.
  • Joined t' motor retainer rin' t' t' MMT with 5min epoxy, makin' sure t' shock cord was wrapped and did nay interfere
  • Joined t' airframe tube t' t' fincan with 5min epoxy, feedin' t' shock cord up t' inside o' t' tube.
  • Added a 1/4" eyebolt t' t' EBay sled that screws into t' nosecone
  • Added an 18" Estes Chute
  • Added clay t' t' nose cone t' get a stability caliber o' ~ 1.5
  • Painted flat black
  • Applied white custom decals (unfortunately, me bucko, no pictures o' t' decals)

After t' rocket gods took Mk1, me bucko, I ran another print for Mk2. Arrr! I tweaked t' print just a bit, but nothin' o' consequence.
