This print can be used to mark climbing holds. This allows you to define your own routes in climbing gyms or your own climbing wall at home.
With different colors special rules can also be defined. For example red only hands, blue only feet, black must be doubled …
With kids you can play games like collect a certain number of a certain color of markers.
If you have some creative ideas for using the markers, feel free to share them in your Makes.

The markers fit into the standard M10 cylinder head screw which is mostly used to fix climbing holds.

There are 2 versions:
A longer which can be easily pulled out of the screws again but may interfere a bit when climbing.

A shorter which interferes less but is somewhat more difficult to remove when the screw is slightly recessed in the handle.

For games where you have to collect the markers I would always recommend the longer version. If really only routes are to be marked, the short ones are also okay as long as the corresponding screw is not sunk too deep. I just printed some of both and then just always chose accordingly :)

I printed everything in PLA, 15% infill.
