Original Prusa Finger Knob

Update Jan 4 2022

So it's been a year, and a few more people have had success and failure printing this. I caved and made the interior almost an exact replica of the Prusa designed 3-wing knob. Lovingly uploaded as version D3.

• recreated the interior knob to match the official Prusa 3-wing design
• got more fancy with the spots for the logo and version number despite being asked not to

If you still have issues with sizing for this one, then I am sorry indeed. I can do nothing more to make this fit like the original Prusa knob, since it's the same innards.

Update Jan 11 2021

• added version number to model
• matched hole diameter to official Prusa MK3S+ knob

I'm sorry it took so long to fix this! I just never think about it, since my original worked fine with no scaling.

Heavily influenced by the Finger Wheel, I remade this to mash together the original knob and the wheel. This way, it completely covers the hole the post comes through.
