S&W 617 Revolver Speed Loader Tray for CCI Box

This is an insert of CCI 100 round boxes that stores 40 rounds in a way that works with speed loaders. There is no space in the box for the actual loader, this holds ammo only. 

I print them upside down but it shouldn't really matter, no supports needed either way (but the fillet might work better if printed upside down)

See my other files for versions that hold 50 and 100 rounds.
