This mod lets you create a minifactory using your equipment grid to produce items for bonuses (move speed, craft speed, etc).
It does not use material from your inventory or produce items for your inventory.

Current end products and effect per item produced:
Transport belt - Running speed modifier +0.005
Inserter - Running speed modifier +0.03
Long-handed inserter - Running speed modifier +0.0375
Fast inserter - Running speed modifier +0.05
Assembling machine 1 - Crafting speed modifier +0.1
Assembling machine 2 - Crafting speed modifier +0.2
Steel chest - Inventory slots bonus +5

You produce end products via machines in the minifactory, from resources created by minifactory spawners (you can only have one of each type of spawner). Then put the end products into an endpoint chest in the minifactory to get their effect for 50 seconds.

Equipment from this mod is meant to be mixed with vanilla equipment for best effect. You can still have personal construction bots as well as a minifactory that makes you faster, for example, and the speed bonus should multiply with exoskeleton speed.

BUGS:
Placing normal equipment first and minifactory equipment after can place things wrong
Fix UPS issue when updating equipment with high counts
GUI stays when removing mod

TODO:
Implement quality
Make mod guidance/info built into the game
Change recipes
Add more effects and end items
Make recipes available only after relevant techs
Add mod settings
Add update proofing to GUI
