Clingby Rana

A lifting edge, two handles and a rope lock, printed in matte bio‑PLA and packed into one box with a frog foot on the side. Finger training that goes where you go.

The method

Strong fingers are built slowly.

Tendons adapt far slower than muscle, a few percent a week. So the training that works is small, frequent, and loaded exactly as hard as you choose.

Cling is a no‑hang: you lift a weight off the floor with your fingers instead of hanging your body from a board. The load is yours to set, and it works anywhere you can put a weight down. No doorframe, no gym.

Anatomy

Take it apart.

Every piece of the kit, from the real print files. The lid slides out on a dovetail, the coupler lets go of the handles, and the rope hardware floats free. Drag to turn it.

Five ways in

One kit. Five tools.

Lifting edge first. Then throw the handles over a bar or branch, pinch the block, pull from the couch, or warm up at the crag before the first move.

Material

Matte bio‑PLA, chalk‑dry.

Every piece is printed from plant‑based PLA made from corn and sugarcane, with a matte finish that holds chalk and doesn't go glassy in the hand.

The frog foot on the box and the handles isn't drawn. It's the outline of the pocket in the bottom of the product, pressed a millimetre into the plastic.

Cling is a training tool, not climbing protection or PPE. Never use it for fall arrest or to support a person's weight in a life‑safety system. Build load gradually and stop if anything hurts.
