New nosepiece that enables the pellet to drop through

I've had a few people ask about using FED3 without a nosepiece, where FED3 would spit the pellet into the cage or other apparatus without trapping the pellet in the well.  In the past I've recommended simply taking the nosepiece off for this situation (I also recommend removing it for testing new FEDs that you build).  The beam break sensor is fast enough to detect a pellet dropping through the well.  However, without the nosepiece the FED3 can experience false negatives if the pellet bounces around and doesn't pass directly through the beam-break to get counted.

I recently designed a new nosepiece that has a hole in it for the pellet to drop through.  I've tested it on a few thousand pellets and it seems reliable so I wanted to share it here. If anyone is using FED3 without a nosepiece you may want to print this one instead of just removing the nosepiece (.STL attached):
