Just a simple tweak to enable this for 0.16 - .0.18+, based off of SableDrake's, https://mods.factorio.com/mod/BiggerStackSizesModded. I simply edited the mod to be enabled for 0.16. it seems to work well on 0.16.35 in single or multiplayer.
Description from SableDrake:
"Makes the stack sizes of items larger. Should work on all modded items. Tested with Yuoki, Bob's and Angel's.
Sizes are configurable in config.lua"
