    Lots of fun stuff one may do with a 3d printer. I've printed a few hose clips and things like that I found on Thingverse, but this is the first diving accessory I designed and printed.

    Some of my diving is during cruises and taking a dive knife on a ship is a pain so I prefer trauma shears. I wanted a sheath that would clip on my BCD's left shoulder strap. The trauma shears snap in the sheath and are held in place by the hinge pin.

    The sheath was designed in Fusion 360

    The shears fit snugly in the printed sheath

    The PT protection clothes cutting tab was ground off the shears as it is not needed.

    Voila!

    I'll be testing it out under water soon and if I am satisfied with this version I'll be posting it to Thingverse and will add the link here.

    So, anyone else design and print 3d stuff for diving?

    I just joined "HackerSpace Gainesville" and now have access to 3D printers. Pretty cool.

    Did you use 100% fill? What material?

    Thanks!

    Will do, and thanks!

    They are quite fun. I'm currently teaching myself 3d design and printing as a hobby so my printer is an inexpensive Monoprice select mini v2, they go for a few hundred dollars on amazon.

    As I am still in the testing phases I'm using PLA with gradual fill (20% inside up to 99% near surfaces). I like the slight flexibility needed to have enough give to "grab" the hinge pin but I'll give full 100% fill a try. When I'm satisfied with the final design I'll try an ABS version, but I'm pleasantly surprised with the PLA up to now.

    I've been fascinated with 3D printers for a few years now. Really looking forward to the test results Pat.D!

    You might try PETG as an alternative to ABS. I've had really good luck with it. ABS can be a bit brittle. PETG is very strong, more flexible, less prone to warpage, and has better layer adhesion. It can be a bit finicky to dial in, but then it's great. Like ABS, it has much better characteristics for diving usage than PLA (i.e., not biodegradable).

    I've used transparent PETG to print diffuser domes for my strobes and other colors for some custom tools that I needed for my rebreather. It's good stuff.

    Keep it up. Your design skills are far better than mine and so far 95% of everything on Thingiverse that is dive related consists of line arrows and cylinder valve covers.
