REMIX

Text from Chris K.

For ease of use, I have added two versions with a Handle. There is one with a 12.5mm recess in order to fit over the axle nut directly and a slightly more stiffer version with no recess.

I relaxed / changed my print settings and can confirm that it works very well for me in PLA with 0.16mm layer height, 6 outter walls and top and bottom layer minimum 1.5mm, 15% infill.

I also flipped the model to the correct side teeth facing upwards as suggested below.

Print time is approx. 50mins on my P1S

The model was designed to tighten a chainring on my home trainer Garmin Tracx by hand. Its not designed for tightening with tools, however I can add a hexnut instead the grip, if requested.

I printed this tool in ASA with following parameters:

4 wall perimeters

6 top and 6 bottom layers

15% infill (adaptive cubic)

Arachne generator for walls

on my P1S with 0.4mm nozzle and 0.20mm Layer height.

The model prints in 8m42s, weights 3.31 gramms and costs about 7 cents
