Hello, I’ve made some parts and tested them at prototype,
crystal for 2520,2016,1612 ; 3535 LED package for apa102, and a PTH micro-USB slot
I focus only on footprint and not breadboard views

crystal footprint for 2520,2016,1612 :
I modified them from the 3225 part available,
and the part print was easily hand-soldered,
so far check with electrometer show no unwanted short happened,
(only ground pads did short)
not sure if they did actually contact, but I’ve once tried placing my working 3225 crystal (on my custom arduino) to 2520,2016,1612 crystal with the same 24Mhz, and all did work on 3225 footprint (so I actually don’t need smaller footprint to use the part, if I had room LOL

4.- apa102 footprint for 3535 version - chained and worked fine, though little bit hard to hand-solder but still pretty feasible, so should be fine for solder-paste.

5.-
micro-USB plug with PTH slot, the holes seemed a bit big, and buggy as it don’t do copper/mask block at bottom-side, still usable as they’re typically grounded
I did another version with oval holes, not working as the oval were ignored and not drilled
here are my tested board, there are also some other testing lipo charger components as well, worked too if anyone is interested
