Trolley Jack Handle

I printed this with thick walls, shell count = 10
My trolley jack is about 20 years old, can't remember where I bought it from, but it never had a handle. When I recently bought a low profile trolley jack (for my MR2 Roadster / Spyder) it came with a carry handle, so I replicated that but a bit narrower for my old jack.

Initially the holes were open, but I figured it would be stronger and look neater with them filled in.
If somebody want's different dimensions, just ask and I'll update the model.
I've included a copy of the model which I created in Onshape, a great 3D package. Feel free to modify this yourself.
