Elliptical Gear Set with connecting links. by PerryT Dec 14, 2012

Description

Elliptical gears and some connector links to play around with. I got the idea for these when i was thinking about an old steam locomotive. I have been playing with them for a couple weeks and wanted to upload something. I may design some more connecting links and different shaped gears that go with this in the future. I will upload them if i do.

Does NOT work with PLA. Don't waste filament on it.

Printed these in PLA (MatterHackers Gold Pro). I was able to get two to fit nicely by aligning your logo and from there I could get 4 to fit together as well (using the flat connectors without the center hole). Good design and fun to print.

Printed these in PLA (MatterHackers Gold Pro) and while I could get two to fit nicely by aligning your logo, I could not put two such assemblies together to get 4 gears in good alignment - too loose even though I matched your pictures (tried the configuration you had with blue gears, 4 of the green connectors with a center hole and 2 of the red solid connectors). Good design and fun to print - I'm sure its just figuring out the proper gear alignment to get it to work.

Instructions

Printing without raft works best for me... with ABS set your HBP to 120c, extruder to 230c and let her rip.... i have printed dozens with no failures. Don't be too forceful when you snap these together. Sometimes one of the 3 prongs will break off on a connecting link. i started out with 4 and had too beef them up and knock it down to 3 to get them to stop breaking.
Please post pics of what you assemble from these... i would love to see them..

ENJOY.
