Universal Handle - WorldBuilder Rollers Set

Complete your terrain-building toolkit with the official Universal Interlocking Handle, the core mechanical component of the WorldBuilder Rollers Set. Specifically engineered for seamless compatibility across the entire collection of interchangeable texture heads, this handle lets you swap textures in seconds to build realistic worlds effortlessly. The handle prints in two symmetrical halves featuring a clever, hardware-free interlocking T-mechanism. Simply insert the pins into either side of your texture roller and snap the handle grips together. The roller stays securely trapped on the axis while spinning entirely freely! Specifications Compatible Roller Width: 68.5 mm Compatible Inner Core: 17.26 mm Model Type: Two-piece interlocking modular handle Assembly: 100% Snap-fit (No glue, screws, or hardware required) Recommended Materials: PLA, PETG, or ABS Features Print-Flat Design: Both halves lay completely flat on the build plate, requiring zero supports. Zero-Hardware Assembly: The robust interlocking puzzle joint tightly clamps the halves together, creating a rigid handle with a smooth, integrated spinning axis. Instant Hot-Swapping: Easily pry the halves apart to swap out your paved stone, brick, or terrain rollers in seconds. Ergonomic Grip: Designed for comfortable, even pressure distribution when rolling out clay, putty, foam, or fondant. Printing & Assembly Tips Orientation: Print both halves flat. Tolerances: The interlocking joint is tuned for standard, well-calibrated machines. If your printer tends to over-extrude, a slight negative horizontal expansion (-0.05mm) in your slicer can ensure a perfect snap fit. Assembly: Place your chosen WorldBuilder roller head between the pins of the two split arms, then firmly press the puzzle joints along the handle together until flush.
