Uses a #2 Pencil for the arrow shaft. One size fits all.
This was part of a last-minute Halloween costume, but it needed some tweaks before it was Thingiverse-worthy.
I'll be here all week! Try the veal.
Cut a #2 pencil in half (a hacksaw works great for this) and attach the fletching and arrow head pieces to the two halves of the pencil.
The bore on the fletching is just a wee bit larger than the arrowhead bore so that you can fit the eraser end of the pencil into it. If the bores are too big, just wrap a piece of tape around the end of the pencil.
Jam the free edges of the pencil halves into the holes on the band. It should be a very snug fit.
