Summary

Two options for holding broadheads, the 'egg' and a plain box that will hold 2 montec style 3 blades (the ones I show pictured are 125gr and 100gr versions)
The egg will hold 125 and 100gr versions also, if your broadhead has vertical play more than you like, a small bit of foam in the tip of the egg would solve this.

For the Egg version I printed one with fuzzy skin and one plain, the fuzzy skin does look better overall but the added grip also helps, so its not just bedazzled, its also practical ;-)
