This arrow rack is good to store your arrows. The arrows are not clipped tightly so this construction is not really useful to transport arrows. Best seems to use 40cm carbon rods to connect. Use damaged arrows or 6 or 8mm carbon rods. There is also a version for 10mm rods. The slits for the arrows. are 8mm wide. Turns out that's a bit tight for 8mm crossbow arrows. So there is a version with wider 10mm slits.

I printed with 20% infill, PLA, 2 walls. You might have to open the 6/8mm holes a bit with a drill for a better fit. Or just force the carbon rods in. Wooden rods should do fine too. You can easily stack up to 12 levels or more. Just seems to get impractical with too much height.

So ten layers will store 100 - 120 arrows.

One version has 12 slits, the other 10. One side has a small knob on top of the connecter . Make sure to glue the rack symetrical. When you glue stack them right on each other with the wet glue so they fit nicely. I messed up in a small way - the left and right side "towers" are not exactly the same width. So make sure you glue them accordingly. Make sure to glue the corresponding sides. I used UHU-Por glue that enables to reposition the rods for a few minutes. CA glue could get the rods glued tight before they are in position.

Update: 10% infill should be fine. Reduces printing times.
