This mod adds a handheld/tool version of Create Aeronautics' Physics Assembler. You can assemble and disassemble your honey-glued contraptions directly from your hotbar.

How it works

It's just one item, and it does exactly what you'd expect:

Right-click a block: Assembles that block (and whatever is glued to it) into a physics object.
Shift + Right-click a physics object: Disassembles it back into normal blocks, instantly snapping it to the nearest grid position and 90° rotation.

Under the hood, it uses the exact same server-side logic as the standard Aeronautics block, so the results are identical.

Crafting

Combine a normal Physics Assembler with two Sticks on a diagonal:

Crafting Recipe

If you're in Creative, you'll find it in the Tools & Utilities tab.

Dev note: Unlike the physical block, this handheld tool snaps your physics contraption to the grid instantly when you disassemble. Since a held item doesn't have a tick loop, it skips the slow, multi-tick alignment animation the block usually does.

Requirements

This is an add-on, so you absolutely need Create Aeronautics installed to use it.
