The OneHandle M

This is a carrying handle for Future Motions outstanding Onewheel+ although it should fit any of the Onewheel models. If you haven't heard of a onewheel, think of a cross between a segway and a boosted board with only one wheel (duh) and no controller. The handle is sufficiently ergonomic to carry the board on those rare occasions when you run out of battery and aren't carrying ianjohnson's Carvepower battery backup.

Updated main body to make all screw holes symmetrical. Rookie mistake. Resized the hole after the mirror command.

Update
Added slightly resized handle to fit SideKicks.

Print instructions

Category: Sport & Outdoors Print Settings

Printer Brand: Prusa

Printer: i3 MK3

Rafts: No

Supports: Yes

Resolution: .2

Infill: Yes

Notes:

Handle is printed in Prusa PETG transparent green at stock temperature settings. Sliced with Simplify3d using two processes. Infill at 15% for the bulk of the handle (Z=0-25 see photo for orientation)while the goosenecks (Z=25.2-71.9) were bumped up to 35% infill. Brackets were done at 35% infill.

When I get the time I will print this in a 98 flex but for the prototype I thought the PETG should suffice. We will see how durable this is. If you do tricks or hard off road on your wheel, go straight to the flex. I use mine to commute so if the wheel is off the ground it's because I am falling or carrying it.

Update
After 400 miles I smacked a curb pretty hard and the handle snapped off. No real surprise. You really should print this in flex with as little infill as possible to maintain the shell. The brackets could still be in PLA or PETG as they don't really take impact load.

Post-Printing

Other Parts

4 X M4-25 Round head bolts
4 X M4 Nyloc Nuts

The holes in the stl file are .1mm larger than the ones I printed so the nyloc nuts should fit better but if they are still tight you can use the bolt to pull them in prior to assembly. They need to be in place or the bolt wont reach them.

M4 Hex Socket bolts would work better but they are not easy to find in small town Canada.

I am experimenting with epoxy smoothing and that may be an option here as well.

How I Designed This

Onshape

The more I use this program the more impressed I am with it. Web based, full featured. Great tutorials and webinars. Engaged user community.

The M in the object name is for Metric. I was going to do an imperial version but the hardware sizes meant redoing the whole thing.
