Ski and pole holder parameterised

Thanks to chatGPT and CoPilot creation of this model was much faster than before. Also thanks to the original author(s).

I wasn't happy with the fixed size of the original model - I need to print clips for 4 people, including kids, so sizes vary a lot. So here it is - the parameterised version. Enjoy!

Be sure to check the final mode thoroughly before printing full size model. Try to print a 1mm-thick sample first to find the best sizing. Be sure to add an extra 1mm in sizing for the sake of plastic shrinking on cool-down. Also give enough space for the pole grips and the bottom parts - they can really get in the way.

UPD: remade the arcs, fixed thickness bugs and circles placements
UPD2: Made rounded corners toggle for the inner squares - most skis are perfectly square without any rounding, also it could be a problem with thinner ski part clip. Still havent found the best sizing for the poles - already broke two prints when attempted to clip-in or unclip the poles, though in
