Motorcycle Jacket Sleeve Vent - Breezy Sleeve

In 2015 I saw a picture of a sleeve vent somewhere (can't find it any more...), and I thought it was pretty cool, so I jumped on Thingiverse and I found this:

So I printed it, used it, and it broke immediately :(. Maybe it was my printer, but I thought it could use some improvement anyway. I quickly learned CAD and remade it, but a lot tougher and a bit bigger. It performs pretty well for me over 70kph. I've taken a set for a lap of the country, and it's still intact. Then winter came and I forgot about it until now. Now, you guys can use it :)

This was one of the first things I ever made in CAD. I'm willing to do a remake if anyone can think of improvements. I'm excited to see any Makes.

Performance depends on the angle that the vent makes with the wind. Turbulence from your bike may have an effect as well. Try both the palm-side and the knuckle-side of your sleeve, or consider adjusting the grip angles.

The gaps in the vents are just a little bit smaller than the types of bees which are local to me. The idea is that they'd get chewed up rather than fly around in your sleeve. Let me know if this works, I've yet to actually hit a bee with one.

PRINTING
Works fine in PLA, should also work in ABS or PETG, but I haven't tried. There's a little rib just above the grille. It's cosmetic only. If you want to print it without supports, drop the part a little below the build plate in your slicer, and it'll sit flat on the grille.

Happy riding!
