I’ve had quite a few requests for the motorized version of the hand cranked Perseverance thing (http://www.thingiverse.com/thing:348489) , so here it is, Perseverance, Motorized. It makes a unique bookend, I receive plenty of inquiries as to where I bought it ( 😉 ). I’ve also printed one using glow in the dark filament for the torso, head, arms, legs, etc., and it looks good, even though somewhat eerie, in the dark. The original has been running over 3 months non stop; it’s quiet, and an attention getter. Video is here: https://www.youtube.com/watch?v=sbmPax3fRTc&feature=gp-n-y&google_comment_id=z12yglrqmqzdhbwy104cepe4dtfstlyohrk0k&noredirect=1. The printing differences between Perseverance and Perseverance, Motorized are the use of “Base Motorized.stl” as opposed to “Base.stl”, the addition of “Gear Motor.stl”, and the removal of “Axle Gear Idler Wheel.stl” and “Knob.stl” which are replaced by printing an additional “Axle Gear Idler End.stl”. You’ll also need a motor, coaxial power jack and power supply. There are quite a number of parts, but all are easy to print. So if your Perseverance is there, print on, and build Perseverance, Motorized! UPDATE: Updated “Base Motorized.stl” with correct tenon Designed using my own software and Sketchup 8, and printed in PLA on a Makerbot Replicator 2 using Makerware 126.96.36.199.
