This is a primer tray funnel. It makes loading square primer boxes into round primer trays easier. I took my measurements from a Federal primer box and one of the round Lee Auto Prime trays.
I also uploaded the source code for this object. Feel free to modify it for RCBS, or other manufacturer's primer trays. Just give me credit for any derived works.

You can also open this in the Customizer and play around with some of the dimensions...

Re: 3D Printed Primer Tray Funnel
If you use the customizer in thingiverse and use
Ring height: 5.0
Outside diameter: 78.0
Inside width: 76.0
Wall thickness: 2.5
it should fit on all primer trays - not a snug fit, but if you first put it over the primer package, lay the primer tray on top and then flip it over, all primers will land on the tray. http://www.thingiverse.com/thing:2205751" onclick="window.open(this.href);return false;
Form customizing it specifically for LEE or RCBS trays, the RCBS primer tray has an inner diameter of 95mm, the LEE (for the loadmaster) 82.9mm
