A simple arrow rack to hold almost any size diameter arrow (I have wood arrows all the way to you 1000 spine arrows). The arrow rack holds up to 64 arrows. Simple model with a top that has 10mm pass through holes, bottom with 10mm partial depth holes, and four corner posts. The posts fit very snuggly into the top and bottom recessed holes which will require a light pounding with your palm on a solid surface to seat them properly. You can add stick on rubber feet if you think they are needed.

I printed all parts in PETG but I assume PLA would work just as well.
