chike bag holder by sanktnelson

I was annoyed by the limited cargospace of the chike cargobike when the children are in the seats, and the extra boxes to screw on the frame are ridicoulously expensive. So I made this bike-bag holder to use with the existing mountpoints for the boxes.
you need:
both sets of printed parts for left and right
6 M8 Bolts
M8 threaded rod ~10cm
10mm Aluminium Tube (<2m)
6 large M8 washers
2 M8 Nuts
Print from sturdy material (ABS or PETG, not PLA) with plenty of walls and high infill. I chose a relatively high tolerance for the holes, because I want to avoid smoothing holes by hand. If you don't or have a much more precise printer, reduce "tol".
The tube and bolts touch inside the parts, so hopefully most load is carried by direct metal-metal contact instead of just printed plastic.
Orienting the parts with the aluminum tube holes facing down (orientation=-90) probably results in stronger parts because the perimeters go around the tube, but may have too little suface area on the buildplate to stick properly. Set tube to false to get the tube sticking out incorporated in the hull, which increases the sticking surface and reduces overhangs. Or maybe you just like that variant better anyway.
