Umbrella holder for wheelchair
Compared to the former version of the device, this one is simpler (only three parts) and will surely take less printing time but maybe it is a little less sturdy (taking advantage as it does of the flexible properties of plastic). It's probably also a bit more limited to umbrella's handle sizes. Compared to the first version, this one allows the umbrella's angle positioning with no tools
I came to this idea the other day watching a fellow getting soaked while he rolled his wheelchair wearing a cloak under the rain. I don't know if you can find somerthing alike in the shops, but he didn't have one and surely he would have found it really handy if he had had it then. So here it is, for the benefit of all of you that are less fortunate than me and cannot walk (but in any case, still like to get out when it is raining).
The device is composed of three pieces of plastic (ABS or similar) to be printed. You will also need two countersunk head screws M5x20 (best would be DIN 10642) and two M5 nuts to fix it to the wheelchair.
The device is designed to be attached to any wheelchair tube from 22 to 25 mm of diameter. The umbrella can be dettached with no tools.
I haven't printed one myself (I haven't got a 3D printer) but I have doublechecked everything and it should assemble nicely (just as all my designs always do !!). Please let me know (firstname.lastname@example.org) if you find any glitches in it or if you think it can be somehow improved, and I will gladly redesign it for you.
So print it and enjoy the sunny side of the street !! (even if it is raining)
