I just attended NARAM-60, which was the first competition of any kind that I'd attended in over 30 years. I haven't even flown a rocket in that time. I expected to be pretty much 'out of it' as far as competition goes (largely correct), so I set another personal goal. I've been 3D printing for the past ~6 years, so I wanted to determine if 3D printed models could be competitive in the performance events (i.e., other than scale bits). So, I printed models for just about every event. I had several good flights, but my inexperience showed in the areas of pistons, altimeters, and cluster ignition.
Never-the-less, my models were mostly different, and I thought the community might be interested in seeing what can be done. As I get the models and posts prepared, and perhaps after a bit more testing, I'll be posting links to them here. The full models themselves will be posted on Thingiverse.
The model that did the best was my C Egglofter. It's 100% printed in ABS, with a dry weight of 21.8 grams. With a few changes I expect I can get that to less than 20 grams. The full story on it is on Thingiverse here: https://www.thingiverse.com/thing:3056609
