The Sea Dart Booster Body! It is important to note that critical to the design of this part is for it to be of a hollow thin-wall design to factor for stability. This part is as light, if not lighter, than the original blow molded design.- Classic estes- style Sea Dart Booster Body (Edited)

Centuri Quasar Fin Unit for BT-60

kcespedes @ccorway thanks I will try in the next 30 days to have it available
kcespedes Try this strategy: use a long 9 inch engine tube and use two rings. one against the edge of the fin unit shoulder and one at the end of the tube. You want two (2)independent points of contact bracing the body tube, and ensuring you don't put a focused point load on the struts with just the shoulder and short 2.75 inch engine tube not bracing anything. Use a long engine tube as a beam to tie the fin unit and body tube together.
kcespedes some folks swear by super glue to saturate strut like elements in other industrial design genres here at shapeways, thought I have yet to try this. My designs are minimal for special reasons, and I would recommend reinforcing where you think applicable, relying on scratch-build sensibility. As a reminder, thought they are resilient, these are aerodynamic performance-based designed objects and should be accounted for as such with regards to launch conditions and safety.
