As you know, I loved the original tiny toy dump truck.  Madscifi showed us the progression of each of the versions leading up to the one that had a movable bed and rolling wheels.  We’ve seen some pretty cool print-at-once things on Thingiverse, but madscifi’s work seems to be opening up a new area with an awesome cam shaft.

His Thingiverse post also provides a lot of detail about how he used manual support to accomplish this print.  The process amounts to introducing pauses into the GCode, putting clay on the platform at the exact proper level, and then resuming the print.

Tiny Toy Dump Truck with Cam Action Bed by madscifi

This is a variation of the Tiny Toy Dump Truck that does require support in order to print. The use of support allows cylindrical wheels, a bed axle sleeve that is no longer sliced, and the addition of a cam and rod that lifts the bed once per rotation of the back axle. It can be printed as a single piece on a standard Reprap/Makerbot by manually introducing support material during the print. See youtube.com/watch?v=47iEXR6xXnE for a video of a working copy that was printed on a standard Reprap.

Maker Bot No.4421 Timelapse from crypto_b on Vimeo.

As you know, we can’t resist a nice timelapse here at MakerBot, so when Thingiverse user Crypto sent me a time-lapse of his assembly process, we couldn’t NOT post it here.

It looks like Crypto’s build was a single 16-hour marathon session crunched down to about 10 minutes — pretty impressive stamina, and the video ends with a successful print.  My favorite part might watching the housecat wandering around at high speed, but that’s probably just me.
