Simple, self-contained, straight-forward, and very useful! To match one Gearery, you need more than 5 Assembler 2's, and the A2's will use more than double the power and take 50% more input. Considering that gears are one of the most widely used intermediates, this is very solid.
The only recommendation I'd make is to increase the power usage to scale closer to a similar output by A2's (775kW v. 361kW).
Thank you for an excellent mod
