Hawaiian Sling

thingiverse

Here is a simple, and very comfortable to hold, Hawaiian sling with spear holder/ end cap. It's 170mm long with 1cm holes for both spear and tubing. Printer Settings: I've gone with a 50% infill just to be sure, but I think 20% will also do. Assembly: Simply print out and slip the tubing through the holes (as in the image) and use a plug like object for the tubing ends to hold the tubing in place. In my case I've used some 10mm RamPlugs. TIP: You could give it a coat of clear spray paint to give it a good seal.
