This was done as a fun, group build at the Chicago Hackerspace, Pumping Station One. The goal was to make a super simple very small delta. It was more for the fun of the build than anything practical.

We used a stationary extruder and a moving build area because it actually made more sense at this size. The build area is about 100mm diameter and about 50mm tall.

To satisfy the people who said it looked upside down, we actually tried it upside down...it worked. See the video here.

There is a bolg post with all the details here and the complete source files are available.

Click view full size on the images because Thingiverse is cropping them in the preview window. On most screen it might actually be full size :-)

Update: I added some recent features.
1: Magnetic base. This makes it easier to get parts of the base.
2: I lazy susan filament feeder.
3: Some lighting.

Read about the upgrades here.

I have access to many types of printers and this little guy is making the best prints of all of them.

While no one has discovered a way to defeat our enemies the Chronophages, the engineers at KONGO! have devised a new weapon to monitor the progress of the time stealing fiends.

Print your own Kongotronic 3000 Series TIME DEFENDER and not only will you never again be in doubt that time IS BEING STOLEN FROM YOU, but you'll know precisely HOW MUCH time!

And you can help improve the TIME DEFENDER! There are expansion ports on the head that have yet to be utilized. There is a submission form upon which you can doodle your ideas. Build the ideas yourself, or send them to KONGO! and perhaps we'll include them in a future update.

Be sure to "watch" this object, there will be updates. Like what? Well, right now there's a hook on the robot's back so it can be hung on a wall, but its tank treads are too long to allow that. Alternate legs will have be made. And doesn't he need a big ray gun to hold?

Don't need a clock, you say? There's plenty of room in that big ol' body to hold other projects. Projects involving meters are a perfect fit.

COMING SOON - PAPERCRAFT VERSION

Hey folks, I'm a freelancer. I put many hours into this project, not to mention countless meters of 1.75mm PLA filament, making sure this would be an exceptional Thingiverse contribution. Heck, I even created a faux package design so you can make a nice gift box. If you appreciate this level of work, if it puts a smile on somebody's face, if you tip well at restaurants, consider some form of patronage. Whether it's a few dimes, a few dollars, or a few meters of filament, I'd be very grateful. I'll even add your name to a patron list on this page. Message me through Thingiverse or my direct email, "kongorilla at yahoo dot com" (please convert to a real address). My paypal account is linked to that yahoo address as well. Thanks!

Need some modeling work done? Contact me for that, too.

PATRON LIST
--------------------
A special THANK YOU TO Bluemetal for becoming the first patron for this project!

davelandia - Thank you for your patronage!
Framingr - Thank you, too!
Trevor L from the Great White North - email me for a proper thank you! (I couldn't reply to your payment)

I wanted to make an extruder that was easier to take off the carraige, easier to check the drive on, easier to clean, and also had fewer moving plastic parts.

So here it is! The motor I use is a geared Nema17 with a 26:1 gearbox (Also tested with a 5.18 which also worked just fine)


The parts are not made in OpenSCAD but I hope someone that is better to use it than me, will make a parametric derivative OpenSCAD of this. :)

Update! The version 1.2 should fit makerbot pulleys.
