Spherical Differential

Description

At some point I might develop this mechanism into something more useful, however for the time being it only serves as an ornament.  The photos are out of date. Check out the stl of the assembled parts for the most up to date visualisation. 

I'm using four 3x10 screws to hold the frame together and one 3x20 to hold the two halves of the core together.

If you have a dual extruder you might like to check out this alternative design for the gears: Gears - Candy Cane Remix

Print Settings:

Printer: Ultimaker 2   

Supports: Yes 

Resolution: 0.4 nozzle __ 0.2 mm layer thickness 

Infill: 20% Notes:

IMPORTANT! READ THIS

The bottom part of the the gears are rather fiddly as only the very tips of the teeth make contact with the build plate. For this reason i have build a supplementary support structure into the stl file itself (see JPG). You will obviously still need slicer generated support structures for all other overhangs, use "touching build plate" rather than "everywhere". For the gears I would also strongly recommend using a "brim" to get better contact with the build plate.

Well done design! I really like how it shows off the capability of 3D printing. The gears printed well, but the stands were a pain, as oriented. Ended up printing them standing up with supports between the base and where the curve begins. The transitition between the vertical and where the curve starts for the support stand is really thin and breaks easily.

This is a pretty fun game, but requires players to have fast hand skills to choose the right arrow keys and at the right time they touch the arrow icons available on the screen to be considered valid. . If you have ever played Audition, you will get used to the Friday Night Funkin game very quickly.

Did humans migrate northward, from South America up to the North American plains? So it's possible that the Clovis' food sources led them into North America. The massive North and South American land masses aren't connected to any other part of the world, and they'd been isolated by the seas for quite some time. While Columbus was among the first Europeans (the Norse before him, and possibly the Chinese and an Irish monk) to explore the New World, he found that the Americas were already inhabited. According to Renny Thomas' study on Indian scientists, atheistic scientists in India called themselves atheists even while accepting that their lifestyle is very much a part of tradition and religion. While there's no tangible value in finding out who got to the Americas first (certainly none of these people survived these thousands of years to accept the honor), then perhaps it's the pursuit of knowledge (and our affinity for ascribing firsts) that has driven scientists to uncover the answer. On the timeline of history, the Clovis people appeared out of nowhere and disappeared in the blink of an eye. נערות ליווי
