PAPA: Portable Aeronautics Physics Assembler
by takl
Players who build flying ships in Create Aeronautics get a handheld tool, PAPA, that assembles and disassembles physics structures in place of the placed blocks.
What it does
PAPA adds a portable version of the Create Aeronautics Physics Assembler that fits in the hotbar. Right-clicking a block with it turns that block into part of a glued physics object, and Shift with a right-click on a physics object breaks it back into ordinary blocks. The disassembled blocks snap to the nearest grid position with their rotation set to a 90 degree step, and the change takes effect at once rather than over time.
The mod works in survival and creative worlds alike. Creative players can find the tool in the Tools and Utilities tab. The mod runs on the same server-side logic as the standard Create Aeronautics block, so results match the block exactly, and the tool can also be crafted by combining a normal Physics Assembler with two sticks set diagonally. It requires Create Aeronautics; the add-on cannot run without it.
PAPA is released under the MIT License and is not open source. Files are published for NeoForge only, for 1.21.1, with version 1.0.0 as the current release, dated 2026-07-05. A server running it needs every connecting player to have it too. Compatible add-ons listed by the author include Create Safe Seating Addon and Addon Create.
Key features
Handheld assembly
Right-click a block to assemble it into a glued physics structure, with no need to place a separate assembler block.
Instant disassembly
Shift and right-click a physics object to return it to normal blocks at once, snapped to the nearest grid position.
Creative-free crafting
A normal Physics Assembler combined with two sticks in a diagonal pattern yields the handheld tool.
Hotbar use
Assembly and disassembly work straight from the hotbar, so the tool stays available alongside other gear.

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