📋 About This Mod
FullFastMechanic expands the abandoned InstantScrews concept with new patches and many extra features: faster screws, machines, fluid refills, car movement, body/interior work and more, all configurable. Inspired by InstantScrews.
Description
FullFastMechanic is a quality-of-life mod for Car Mechanic Simulator 2021 focused on speeding up repetitive garage actions.
It started as an updated and expanded take on InstantScrews, which was no longer being maintained. I decided to patch the original concept and extend it with many additional features for screws, machines, fluids, vehicle movement, bodywork and interior parts.
Most timings and speed multipliers can be customized through the mod configuration file.

Shout outs
Special thanks to the author of InstantScrews:
https://www.nexusmods.com/carmechanicsimulator2021/mods/104
InstantScrews served as the original base and inspiration for the screw interaction mechanic.
Since the original mod was no longer receiving updates, I decided to maintain and expand the concept with new patches and additional features.
Development, debugging, refactoring and code assistance were also carried out with the help of GPT-6 Astra (for large-scale features, debugging and optimisations).
All updates are fully tested in the latest and stable versions of the game, which are official and available on Steam.
