Nerf Arrow Short

This is my take on a short nerf dart just took the dimensions and gave it my own “spin”.Should probably be printed in TPU because in PLA those things are pretty damn hard. The idea was to make darts that are hollow on the inside except the tip, to make them tip heavy and lean toward the mass (tip). Then i thought, spirals are cool, as they are the only geometry connecting all points of a surface… and give ammo a stabilising rotation. I have yet to print and test it in TPU. Test with PLA with 1 spiral/bottom/hollow&full/12.75mm seemed promising, but it is a bit loose in my “leedle maraca stringshooter”.(that's why I made 13mm models too) This is for a toy gun, that takes ShortNerfDarts. There are several Print Plates all named accordingly:There are 4 differences in each model (spiral/dart):(hollow/full):(bottom/open):(13mm/12.75mm)A P1S build Plate can do +200 darts if filled (up to 285) that takes around 35hours to print and 1037g of filament (thats PLA for the 100% infilled full s
