I found that it was hard catching my resized cases from the Lee Automatic Processing Press (APP,) so I got a square funnel from Amazon and made a guide to direct the cases into a bucket or box under my bench. The spout was a little too narrow for .45 ACP cases, so I cut off approximately 1/2" (12mm) from the bottom to enlarge the hole. Additionally, I used a strong magnet to attach the funnel to my bench in the right position. The guide simply friction fits onto the spout. I've included the SCAD in case you want to tweak it.

I printed this standing upright on the belled end with no supports. I used a brim to ensure good adhesion since it is a little tall and I didn't want it to topple during the print. Clean-up was super easy with no stringing inside.
