I would like to build the crazy gear clock but I really like the mini version as opposed to the medium or large one. Can I buy the SP10 plans and just scale them down? If so, what scale would you recommened to replicate the one you show in your videos? Thanks!

Is the smaller crazy gear clock just a scaled Sp10?

So I did manage to scale this one down. here was my process if anyone wants to follow:
assemble the entire clock in fusion 360 then scale the whole model by 75%
redrew all the gears since I liked the look of chunky clock gears versus the more organic gears that were included. The shaft dia. is fixed in fusion at 2.4mm accounting for some overextrusion a bit. The gear modulus I used was 3 I think. I used the original gears as the reference to give the outer and inner gears the same orientations and to get the thicknesses just right.
the front, back and lower base were also increased by 1% in the x/y direction to give the new gears a bit more play. The base was then stretched in the z direction back to the original height to accomodate the electronics.
the base was also remodelled a bit to make room for the nema17 motor--I could have stretched the legs but I had them printed already and didn't want to redo it :)
