Glue
by Remero
Glue gives pistons the ability to shift chests, hoppers and other block entities, a movement vanilla pistons cannot perform.
What it does
Glue is a Fabric mod for Minecraft 1.21.11 that lets pistons move block entities. Applying glue to a supported block locks its contents in place so it stays where it is when a piston pushes or pulls it. Block entities keep their data and inventory after they move, which makes mobile storage and compact automation builds possible in redstone designs.
The mod works with storage and automation blocks, including trapped chests, and with crafting and utility blocks such as crafters and note blocks. Glue is applied as an item, and an axe strips it off again, much as an axe removes wax from copper. Some special or complex blocks are not supported yet, and placing blocks in invalid positions can cause problems, so builders should test unusual setups first.
Glue needs Fabric API as a required dependency. Fabric Language Kotlin is bundled inside the mod, so no separate install is needed for it. Both the server and every player need the mod, because it is client and server. The code is under the MIT License and is not open source.
Key features
Piston movement of block entities
Pistons can push and pull supported block entities that vanilla pistons leave in place.
Glue locks
Applying glue to a block keeps it from moving with a piston, which helps prevent unwanted displacement.
Axe removal
An axe removes glue from a block quickly, so a lock can be reversed without breaking anything.
Data retained on move
Moved block entities keep their names, inventory and other data, so storage can be relocated intact.

Use cases
Who it’s for: Players building redstone circuits, automated farms or movable storage on Fabric servers and single-player worlds, where both sides run the mod.
How it compares
Old Piston Sound Engine is a client-side only Fabric mod, open source under the CC0 1.0 Universal license and published for 1.21 – 1.21.5, so it changes sounds without touching block movement. Smart Placement is also client-side only, open source under the MIT License and covers 1.21 – 1.21.11, so it changes placement rather than piston behavior. FastHoppersLove is server-side only, not open source and built for 1.21.11, so it targets hoppers on the server alone.

What the author says
Move block entities with pistons — lock them in place when you don’t want them to move. Glue allows pistons to push and pull supported block entities such as chests, barrels, hoppers, and more. This opens up new redstone possibilities, mobile storage systems, and compact automation builds.
