Lee App / Breech Lock Pro / 4000 / Six Pack Pro / 6000 Case Feeder

Note:  this is a work in progress.  It is working really well for me but ymmv.  Please provide feedback for improvements.

This is a case feeder for the Lee Precision APP, Breech Lock Pro (4000), or Six Pack Pro (6000) press.  The feeder that comes with the press is an incredible pain to use as to change case sizes you have to adjust the height and to change between large and small diameter cases you have to disassemble the entire thing.  This feeder uses interchangeable adapters so that there is no need to readjust.

Unlike other designs, all that is needed is 3 M3 screws.  1 M3x12 to connect the tube holder to the base and 2 M3x20 to use as pins to hold the adapters in place.  The latter can be replaced with anything appropriate as it doesn't screw in, just slips in and out to hold things together.  I used finishing nails in early testing.  TBH they're not strictly needed but might be nice if you are being particularly aggressive.

Currently I have only provided adapters for calibers I commonly load, as  I don't want to release anything untested.  I will happily provide new ones in exchange for testing.  Please post a make (so I know you have a working model, i.e. no point in testing if your tolerances are WAY off :D) and send me a message with the caliber you want.  If your testing proves positive I'll add it to the library.

Print settings are pretty easy.  Nothing needs supports, use brims as needed for your printer.  I used 0.16 and PLA.

Note 1:  The down tubes for the adapters are intentionally tight on tolerance.  If they are too lose the cases drop too fast and can lead to them jumping forward or double feeding.  The slight friction slows them down and prevents this.  As such, you may have to push a few cases through to loosen them up a bit when first printed.  10 or so should be plenty, if that's not cutting it you may want to look at your wall and seam settings.

Note 2:  This is similar to another design that used to be available but it is 100% designed from scratch.  The author of the previous design got greedy and decided to pull it after he started selling them (for more than the cost of the whole press!)
