EQ3-2 CW bar locknut spanner

thingiverse

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. Print Settings Printer: CTC Rep dual Sailfished Rafts: No Supports: No Resolution: 0.20 / 0.25 Infill: 100% Notes: I think PLA has a place in 3D printing and this seems to be the place for it PLA has more of a spring and give over ABS so I suggest, if you print this to give it a go if you have some PLA handy.. The printer recons its used about 11.5 meters of fillament (1.75mm) but how true the guestimate is is anyones guess. I printed this with the dreggs of 2 rolls of PLA that were lying on the shelf waiting on a random small job that would use them up so the pictures show it as half yellow half white. ABS may work for this spanner but I think the small lugs that lock into the nut may be too delicate and just break off the first time you use it, but feel free to try it in ABS and let me know. How I Designed This As always this was started in Tinkercad and finnished off in 123D..... R.I.P 123D you will be missed when your are gone.
