Mechanical Parts Mod

This mod introduces gears and mechanical components designed for contraptions, engineering experiments, and complex builds.
Whether you're building a simple pulley system or a fully-functioning engine, this pack has you covered.


Accelerometer – Measures acceleration and movement speed
Cooler Propeller – Converts rotation speed into thrust
Combustion Cylinder – Converts fuel into motion
Steam Piston – Converts water and heat into motion
Liquid Distributer – Distributes a precise amount of liquid
Cam and Follower – Sends out an activation signal when pointing towards a certain angle
One-Way Bearing – Allows rotation in only one direction
RPM Limiter – Limits rotational speed
Simple Gear – Less complex gear for high RPM applications
Gear – Functional gear
Toothed Rail (Rack) – Works with gears to create linear movement
Shock Absorber – Dampens motion like a real suspension
Customizable Shape – Customizable polygon maker
Fast Counter – High-speed counter
Rope Winch – Wind and unwind rope with torque
Inert Liquid Flask – AKA water
Claw – Mechanical gripping device
Pulley – Changes direction of rope force
Mechanical Coupler – Only Attaches to other mechanical couplers
Dynamo – Changes Mechanical force to electricity
Burner Unit – Burns Oil/Nitro to create pressure that can be used in other pressurized containers
Boiler Unit – Boils Water to create pressure that can be used in other pressurized containers
Turbine – Uses Pressure to create torque
Gas Valve – Toggles Pressure transfer between pressurized containers
Gas Dumper – Dumps all types of gas
