Piston Range Display
by Ragek34
Piston Range Display draws the push reach of pistons in the world, so players can see the 12-block limit before they build.
What it does
Each piston is shown with a boxed outline that marks the area its push can reach, and laser-style lines can be used instead for a lighter view. The overlay appears when a piston is in view, and it can be set to show only the piston the player is looking at. Pistons the player has already passed are remembered through a local cache, so their ranges can still be read from the same spot.
The display is client-side only, so the server does not need it and players join without installing anything. The mod is published for Fabric alone, with 1.0.0 for 1.21.1 as the latest file, released under the MIT License. It is not open source. Fabric API is not listed as a requirement, and no other mod is named as a dependency.
Key features
Push range boxes
Classic three-dimensional boxes mark the block range each piston can move, so limits are visible at a glance.
Look-only mode
The overlay can be limited to the piston under the crosshair, which keeps large machines readable.
Remembered pistons
Pistons the player has encountered stay in a local cache and keep showing their ranges.
Adjustable colors and rendering
Colors, transparency and render modes can be changed in the configuration menu, which opens with a default key.

Use cases
Mapping machines
Players laying out a piston-based machine can see every push area before placing blocks, including across a large build.
Quick checks
A single look at a piston shows whether the block it targets is within reach.
Who it’s for: Players building piston contraptions in single-player or on a multiplayer server, who want to check push limits in the world rather than work them out by hand.
How it compares
Hand Pistons runs on the client and the server together, is available for Fabric, Forge and NeoForge across 1.21.1 – 1.21.11, and is not open source. Piston Push runs only on the server, is open source under the MIT License and works with Fabric and Quilt for 1.20 – 1.21.8. Piston Range Display, by contrast, needs only the client, works only on Fabric, and covers just 1.21.1.
