Pop-Lock Telescoping Back Scratcher:

The Pop-Lock Telescoping Back Scratcher is a print-in-place, mechanically adjustable tool designed to demonstrate functional motion through telescoping extension and controlled part separation. The handle extends to increase reach for hard-to-access areas, while the scratcher head features a pull-off, quick-detach interface that allows it to be used independently for closer or more precise scratching.

This design combines a telescoping extension mechanism with a friction-fit pop-off end, creating two distinct modes of use within a single print. The telescoping body provides adjustable reach, while the detachable head transforms the tool into a compact, close-range scratcher without requiring additional components or hardware. To reattach the head once disconnected (or in short mode) simply re slide it back into the handle/body in any way, which then will switch it back to expandable mode, and vice versa for short mode (simply pull the head out with moderate force)

All moving parts are integrated directly into the print, emphasizing print-in-place engineering, functional transformation, and user-driven mechanical interaction. The design focuses on practical ergonomics while showcasing controlled motion and modular functionality.

This model highlights mechanical intent, adjustable geometry, and multi-mode functionality.

Key Design Highlights:

Print-in-place telescoping extension

Quick-detach pop-off scratcher head

Dual-mode use (extended reach + close-range control)

No additional hardware or assembly required

Compact and mechanically efficient design

Printing Recommendations:

Print vertically as oriented in the file to ensure that the telescoping function works correctly as shown in image:

Print with tree supports in order to support the head of the scratcher.

PLA+ or PETG recommended
