Parts for building a 2 stage LPR model rocket. Motor mounts for 18mm motors in a 24mm (BT-50) body tube. Motor mounts are complete with staging coupler. Nosecone and plug/Coupler allow for a payload bay (can be clear tube). Rear engine retainer cap is styled after the rolled embossed cardstock booster tail from the out of production 1970s Ested Astron Shrike. Also included are models for a display stand with 2-material Shrike head medallion (glue in place).
I've printed these parts in PETG. They flew well in a clone of the Astron Shrike. Flight went well but the booster's staging coupler did not survive ground impact on pavement. I didn't have much faith in the sustainer stage engine retainer cap, so I made sure to have a solid friction fit to keep the motor from blowing out.
