yooper69 and shellhouse,
The owner replied it was ok to print for "club members." Was appreciative that I asked at all. I re-asked, repeating that it was for Forum members, not club members, but got no response to that part of my message. Is it Tom in CA who says not getting a no is the same as getting a yes? lol So the picture is what I have handy. Two printed directly from the file, and one I modified with thinner ears so it could use the stock nut and bolt. They fit my 11" equinox coil, and should fit 15" as well, but untested. These are for "thin ear" coils, I'm told Minelab is now making them with thicker ears?
Printed fast and solid, not pretty, but functional. I recommend not just jamming these on your coils -- make sure they don't force the ears inward. A tiny bit of filing where I've circled in red (on both sides) is strongly recommended. I'm not responsible if these cause your ears to break!
Anyway, these three are up for grabs, __to you two__, who previously expressed interest in getting one or two. LMK what you want. I could print off either style again. Not my design, so I'm not profiting off them -- A buck each, plus the painful $4 USPS shipping. I'll have to scrounge up shipping materials, but should get them out pretty quick.
Oh yeah, I can print some thin spacers to go behind the rubber on your coil shafts if you are interested, no charge. They're roughly 0.010" thick virtually no plastic cost.
For the future, and anyone else interested in these items, I'm in process of designing a new slightly larger bracket that distributes forces to the coil body, and doubles as a repair bracket. But that's down the road a ways.
