The cycling bag will be sown on top and 3 hose clamps will be used to attach it to scooter tube. Default values are measured for this bag from aliexpress.
- printed holder (obviously)
- three hose clamps (min. diameter 60mm)
- bicycle tube to put under holder supports and hose clamps - to avoid scratches
- needle and thicker thread
Edit: model is done, I only made holes for thread a bit larger (0.8mm -> 1mm).
Edit 2: after close inspection of printed holder, some mistakes were found. Holes were made bigger, because some printers were making them smaller. Code was also bit refactored and most important dimensions were put on top.
