I noticed Adafruit recently added a set of stacking headers for their ItsyBitsy processors that use two rows of 14 pins with one row of 5 pins in the back. That seems like a familiar size. In looking at the part number (3883) they presumably added it some time ago, but it just popped up in the new product page.
If somebody wanted a pair of 14 pin stacking headers and one 5 pin stacking header, you can order it from Adafruit. Adafruit also has low profile headers for the ItsyBitsy form factor.
FWIW, Sparkfun also has a similar set specifically for the Teensy 3.2, but their kit is now 2 13-pin headers + 1 7-pin header. This means if you can't use it for things like the audio shield which has 14 pins but does not bring out the back 5 pins. I had remembered the Sparkfun kit from when they were first released, and just ordered a few from Digikey. I didn't notice that it had changed from the 14 pin setup. That being said, it can be rather tight to get the 5 header in, and the 7 pin header is probably easier to solder:
Normally I just take longer headers and cut them down with diagonal cutters. But it takes using a rotary tool like a dremel to get the headers so they are flush and can be packed into tight spaces. Also every so often I cut the header too close and the last pin comes out.
