<p>Wrench for tightening / loosening star locks for your dumbbells / barbells. I usually can't get them tight enough and they come loose after a few reps. With this wrench you can tighten them much better.</p> <p>See Picture 3 for Dimensions. I have 8 of those nuts. It fits perfect on 6 of them. On the other 2, the fit is very very snug. Probably a production error since the teeth aren't spaced even on them. You might want to check your nuts before and print the file a smidge larger.</p> <p>DE:</p> <p>Schlüssel um Sternverschlüsse von Hantelstangen anzuziehen. Bekomme die meistens nicht fest genug, und nach ein paar Wiederholungen lockern sich diese Verschlüsse immer wieder. Mit dem Schlüssel bekommt man sie viel fester, funktioniert viel besser.</p> <p>Have fun &amp; keep lifting ;-)</p> <h3>Print instructions</h3><p>I printed it with 5 Perimeters and 10 Top &amp; Bottom layers to give it very good strenght. I don't know if PLA will be strong enough. Might break. PETG / ABS is more elastic and suited better for this application.</p>
