InMotion v10/v10F parking stand

This stand allows you to park the EUC on flat ground without leaning on anything.

Based on original model from ffonta's (and remix from Laggerko) work. I found the previous versions to be too narrow and would tip over at the slightest bump. I have widened the base surface area by about 2x and found it to be much more stable

PETG is probably best as it needs to be tough and weather resistant

I just used the default 0.20mm setting on Bambu slicer for the a1 mini and it works great 👍
