T-Rex Windup Walker

Did you purchase the "Windup Walker" at Makerbot.com (http://store.makerbot.com/windup-walkers.html)? If so, you can remove the windup motor and build your own "T-Rex Windup Walker".

Video of "T-Rex Windup Walker" on YouTube at "http://www.youtube.com/watch?v=anOImtxokow".

Designed using Sketchup 8 (free version), and printed on a Replicator 2 in PLA using Makerware.

Carefully disassemble your windup walker. Begin by releasing the clips on the bottom of the walker, then carefully slide the components apart. All we are interested in is the windup motor assembly, but save your other parts just in case you want to restore you windup walker.

Purchase some "thick" cyanoacrylate glue. Accelerator is also useful to save time.

Carefully study "Assembly.skp".

Print one each of all parts except print two each of "Cap Pin.stl". I printed all parts using Makerware "Standard" settings.

Slide the windup motor into position (curved end down) in "Body.stl" as shown in "Assembly.skp", then center it and apply a small dot of cyanoacrylate at the corners to hold it in position. Pay close attention to the orientation of the windup handle, it must extend from the right side of "Body.stl" as shown in "Assembly.skp".

Press "Arm Left.stl" and "Arm Right.stl" into "Body.stl" as shown in "Assembly.skp". A small dot of cyanoacrylate helps hold the arms in place.

Place "Retainer.stl" on "Leg Right.stl", then position both as shown in "Assembly.skp".

Slide "Leg Left.stl" inside of "Retainer.stl" into position on the left side of "Body.stl" as shown in "Assembly.skp"

Slide "Pin.stl" into "Body.stl" and center it as shown in "Assembly.skp". Make sure "Pin.stl" is between the fingers on "Leg Right.stl" and "Leg Left.stl" as shown in "Assembly.skp".

Press one each of "Cap Pin.stl" on each end of "Pin.stl" as shown in "Assembly.skp". Place a small dot of cyanoacrylate on each to hold in possition.

Windup and watch "T-Rex Windup Walker" traverse your keyboard!
