This is a derivative of the filament spindle made by Erik on Thingiverse.

This is designed to operate along side the Makerbot rather then the RepRap. Because the Makerbot Cupcake CNC does not have the same structure that the RepRap does, the original design does not work. By attaching the stand we now have a standard spindle which works with any system.

Problems that still need to be addressed:
- Spindle spins so freely that the filament itself would probably unwind itself slowly. In the future i would like to add a screw that can be tightened which adds friction to the sides. Keeping the spindle from spinning 'too' freely.
- The Spindle is slightly underweight and with enough lateral force could topple. To address this issue simply attach something heavy to the base. Or add an additional acrylic piece perpendicular to the current stand to increase the base size.

The human powered internet cafe looks at the issues of renewable power generation and aims to educate users to the energy requirements of surfing the internet.

Users are asked to peddle the exercise bikes in order to turn a dynamo which would in turn power the computers. If users fail to peddle hard enough the computer monitors will begin to flicker encouraging them to peddle harder.

The thing would ideally be placed in public areas where all forms of society could view it and try it out for them selves, thus educating as many people as possible.

It is printed in red PLA with a mendel reprap. The slices are 0.2 mm to gain the details needed for printing in original size.

For that I just resized it to the size of standard lego (exactly factor 0.5). Because of the miniaturisation I had to change the hole for the clamp of the hips. Also I slightly increased the size of the arms for a better fit to the hands.

I glued some nails into the arms and put them into the holes of the torso. Now you can also move the arms!

For a better fit to lego bricks I cut of two squares into the legs - now it can stand on lego :-)

This is my design of a peristaltic pump or hose pump if you translate it directly from german.

I built this pump for reseach to gather basic hands-on knowledge of the inner workings.

If you have a MakerBot/3D Printer you can start right away. I built it in a few hours with common parts i had at hand.

Unfortunately you definitly NEED a very flexible silicone tubing, to get it really working. I did my first try with a short piece of tube i cut from our fish tank - this was definitely to hard for the ABS. unfortunately i was to eager to pump some water, so i did, but the contraption got too hot and broke.

The Pictures are from the rebuilt, but this time i'm waiting to get the silicone tube.

Currently there are no mounting holes for a motor. i used my electric screwdriver for testing. Gearmotor is planned, but i had to determine the required torque with this build.

This is the new PRotos 3D-Printer designed on the base of Mendel/Prusa to build up a more versatile printer wich is expandable for different applications.

This is a lotus or rose or what ever is most Awesome. I made this as a gift for someone so I went the extra mile and made some brass leafs colored green and Copper wire stems so oxidize them in a brown green tone. I went to TIG the copper to the stainless stalk but It was too small so I just brazed it. I ended up Threading the stem to use a 4/40 nylon acorn nut below the flower and a 4/40 acorn nut at the top to look real.
