A small arrow square tool i threw together. It's primarily for the 5 mm ID arrows like Easton Axis & FMJs. It should work from the get go with the micro diameter InjeXions, but might need a little sanding to properly get a snug fit for regular Axis & FMJs.

Personally i used 5 mm FMJs 300 spine with the .273 OD and needed to do a little bit of sanding to get a good fit.

Cut up a bit of sanding paper, glue it on the inside of the lid, slide the lid on and you're good to go!

Depending on the tune of your printer i'd make sure the piece is totally straight with a bubble level. Mine was good but you never know.
