These are for dangling from your rear bumper/trailer hitch to show off your truck/jeep/suv's manliness. They are approximately 5 3/4 inches at their widest point. Put them on your Suzuki Samurai to show off just how buff it is! Print them in flesh color for ultra realism!
Put them on a pink Jeep Wrangler with a doily wheel cover to bring out it's hidden masculinity! (doing this from experience!)

All you need to know to print these is you need at least a 150x150 bed Print it in .3 layer height with a 5% infill.

When the print is done, detach it from the build plate.Then you will need a 1/4 inch eye bolt with 2 7/16 (outside) nuts and a 1/4 washer. (the hole on top is 6.5mm with a 11.5mm hex hole if this helps all those outside the SAE world) Put one nut in the hex hole inside and the washer and other nut on the outside and thread the eye bolt through the hole, then tighten the nut outside down to secure it!

When all is finished you can paint it if you desire and attach it to your respective vehicle in a manner you see fit! (I used quick links)

I printed them in PLA but ABS would be a better choice for outdoor use. If you decide to use PLA I recommend you at least spray paint it to keep them somewhat UV / weather resistant.

For the Love of Sanity don't print them in LIME GREEN! Just so wrong...
