Arrow for Rubber-band Bows

thingiverse

I'm designing an arrow with rubber-band bows, featuring a diameter of 6.25mm and a length of 160mm. To achieve a snugger fit, consider scaling it up to approximately 7mm in height or slightly taller, possibly requiring supports at the tip. The first STL file displays a more spear-like design, whereas the second file features an arrowhead connected directly to the shaft.
