A little bit more space between the ball and the handle, then in the
original model.
And also want to make it printable with color change.
Update 08.01.2023:
The model is a little bit reinforced, so it shouldn't brake so fast.
There is also a model with support and a tower for color change (purge block)
But the whole thing is really fragile (cause of the color change option) so it shouldn't fall of the Table or it will break.
Update 14.01.2023:
Modified version, so the parts are seperatly printable and the color could be changed easyly.
It's also more stable
see here.
A crash from a table doesn't matter.
It doesn't run quite as smoothly as the other version, you may need to adjust the orientation of the stem a bit.
The tolerances are matched to my printer.
