Climber Prototype
We are working on a climber that uses a tape measure or fish tape.
Our Progress
We are prototyping a small, two-stage telescoping arm.
Materials:
Stages:
Base: 1" Poly Pipe
Stage 1: 3/4" Poly Pipe
Stage 2: 7/16" Dowel Rod
3D Printed End Caps Onshape Link
Tape Measure
3D Printed Spool for Tape Measure: Onshape Link

After some trial and error with the 3D printed fittings, assembly is starting to come together.

Worked on the tape measure spool, and determined it needed a cover to help make sure the tape was contained and did not unwind too much.

The "proof of concept" is there, but we learned a lot, and would make many changes.
Tape measure is flimsy and this method does not reliably extend the tape measure. Extending the tape measure works, but not very well.
