Fully 3D-Printable Extension Arm for Philips MG5720 – OneReachPrint

OneReachPrint – Adaptive Back Grooming Extension for Philips MG5720 – no tools, no hardware, just print and groom

After developing the original OneReach, I wanted to revisit the design to make it even more accessible for home users – with no special materials, tools, or hardware required.
So I reduced the size, removed the screw inserts and Velcro mount, and optimized the geometry for common 220×220 mm print beds – making it fully printable on most household 3D printers.

Instead of using a Velcro strap, OneReachPrint features four integrated hooks that let you secure the MG5720 trimmer with a simple rubber band – something most people already have at home.

Key Features:

• Fully 3D-printable – no screws, no glue, no hardware
• Fits standard 220×220 mm print beds
• Max. Reach: 49 cm
• Threaded connector – secure, tool-free joint using printed screw
• Rubber band mounting – holds the trimmer safely in place without modification
• Compact design – slightly shorter than original OneReach but still covers the upper and mid-back comfortably
• Quick and easy to assemble – no tools or fasteners required
