EQ3-2 CW bar locknut spanner

After having a super strong moment a few weeks ago I managed to tighten the locking nut that tight that I could not get it loose on my Skywatcher EQ3-2 counterweight bar. Not wanting to attack it with grips and the likes I decided a simple spanner would work, well at least I hoped it would work even if it died in the process of looseing it off.

Printed at 100% with 3 shells in PLA I think it will be far stronger than ABS for the job its gonna do and to my supprise it seems pretty good because I had the nut loose in seconds.
