Mk2 version - a bit less weight, printed with S3D /75% fill/standard S3D support
Disguising a long Spreader Bar when flying or going to a Hotel can be a challenge - my Clip-Together All-Plastic Spreader Bar will fix the problem.
How many sections do I need
The MALE End is 40mm long, female and Joiner sections are 90mm long.
So both end sections and 4 joiners gives 580mm total length, or 6 joiners = 760mm.
I used ABS with S3D standard support & 80% infill - less infill % may be OK, but who wants a subbie getting loose (without her safeword, of course)
A small amount of filing so the parts easily twist together and lock, and you're good to go, - but not your sub - who isn't going anywhere.
