Sprocket Idler for Treads by LoialOtter Nov 27, 2012

Description

This is an idler with teeth to increase the ability to hold the tracks in place. If attached to a power source somehow they'd be able to drive the treads but that was not my intention (I'll be making one of those soon based on this design).

This is for: http://www.thingiverse.com/thing:35668

The length between points was found to be different than expected through trial and error.

Sorry - Had to update... it helps to double-check that the hub doesn't interfere with the gear part of it. Now fixed.

And one more fix - I should really test before releasing my items. hehehe. Adjusted outside diameter of teeth down quite a ways. Adjusted width of teeth up a bit and made angle a little better for printing.

Instructions

I printed at 0.4mm layer height and 25% infill with solid every 8 layers, this may have been overkill.

Fasten wheel in place with #10 or 5mm screws (might need a little filing with 5mm) remembering washers both sides of the hub.
