Description

This is a model that should be printing very soon, but I decided to go ahead and upload it.  These gears should turn on the base, and would make a nice conversation piece, and will hold pencils, pens, et cetera.  I designed this to be printed all in one print, but it would certainly look better if the parts had various colors.  I designed it with zero fasteners, so I made my first "pop-in" axle design.  I hope it works!  I'll post photos of mine when it's finished (if it prints at all).

I've printed this object, and it does work... even though my print quality was horrible, at best. (I'll post images ASAP.) This version took over 16 hours to print, and ate up quite a bit of black PLA filament. I printed at 205 degrees nozzle/60 degrees bed with 10% infill... 0.30mm layers with no raft, brim, or supports. My quality issue was due to lack of a proper filament spool holder on my DaVinci 1.0 Pro, and my current arrangement puts a lot of strain on the extruder stepper motor. (This will be fixed ASAP.)

But in the meantime, I re-worked the design to use a LOT less filament and take a LOT less time. The base has hollowed-out areas to reduce volume, and the walls of the gears are only 0.8mm thick. I've re-designed the mounting pins so that they are much larger diameter, and will require a wood screw and large washer in order to fasten the gears permanantly.
