Archery Arrow Fletching Jig

I added some support / stiffeners bars to prevent wobble and flexing while printing. Cut them off afterwards. A flame gets rid of any left over stringing.

Original description.
A nice little tool to help you mark the position of your 3 arrows, at 120 degrees from each other. There is a nocking point within, so that your cock feather is perfectly 90 degrees from your string! Fits shafts up to 9mm diameter, and 4" feathers.
To get it on with an existing cock feather, just bend the open part of it and slide it over! Works fine with me 4" x .5" vanes. Sharpie works perfectly.
