3D Printable WW2 Enigma Machine Replica

Pascal and his students made a replica of WW2 Enigma encryption machine with 3d printed mechanism. It is a very interesting project and you will learn something more about encryption.

All the code, files and instructions can be found at:




Here are two videos that explain Enigma machine and the science behind it:

Star Track 3D Printable DIY Astronomy Pointer and Tracker

Görkem Bozkurt developed an Arduino powered astronomy pointer and tracker that can be made on a DIY 3d printer.
It could probably be customized to move a small telescope or asrophotography setup.

He described his project as:
Star track is an Arduino based, GoTo-mount inspired star tracking system. It can point and track any object in the sky(Celestial coordinates are given as input) with 2 Arduinos, a gyro,RTC module,two low-cost stepper motors and a 3D printed structure.

Do keep in mind that lasers are dangerous and that there are strict laws against pointing at airplanes.

Very detailed build guide can be found at:

3D Printed Automatic Sunglasses

Yousif Ashoor developed a 3d printable sunglasses that automatically move to cover his eyes when exposed to sun.
He wrote that he did it: "To protect my virginity and my eyes". Mission accomplished.

But seriously: Cool shades bro! Cooooooooool shades. Share the design. It could become the new style.

DIY Silicone Nozzle Cover

One way to protect your nozzle from getting dirty is to wrap it in a cover, sock, sleeve or boot and prevent all the hot nasty stuff sticking to it. E3D released their silicone sock for Vulcano nozzles but someone found a way to make a DIY version.

Ubermeisters used 3d printed model of the nozzle and made a mold around it and than used some high temperature silicone mixture to produce the final cover. All steps are photographed in detail.

Here are the files and the instructions:

And here is the E3D sock:

Ultimaker 3 is released!!!

Much anticipated Ultimaker 3 is just released in two versions, where one version is extended with bigger print volume.

Key features include:
  •  Build volume of 215 x 215 x 200 mm and 215 x 215 x 300 mm for the Extended model
  •  Layer resolution up to 20 micron for 0.4 mm nozzle
  •  Print temperature up to 280 ˚C
  •  Dual extrusion with a soluble support material
  •  Swappable print cores
  •  Heated build plate with active leveling

It is priced at 2995 euro for Ultimaker 3 and 3695 euro for Ultimaker 3 Extended without the VAT.

Promotional video:

Here is the video overview of Ultimaker 3 new features:

Here is the video with dual extrusion of a gyro model:

The design of the machine is very simillar to previous model:


Here is what looks like test print of 3D Benchy with dual extrusion of two colors:

How to 3d print GPX data

Thingiverse user "snrk" aka Per from Sweden shared his method of converting .GPX data from a GPS in 3d printable files. He used Processing to with additional libraries to  parse the files and translate the data to points in a voxel array.

Here is the example of 3d printed run data recorded on a GPS device in .gpx format:

What if you could carry a small 3d printer everywhere?

What if you could carry your 3d printer with you as a small bag? What if 3d printers were everywhere? Researchers at HPI explored this possibility with actual hacked 3d printers and 3d printing pens to  test the implications on everyday life.
It would basically give you magic power to repair and replace everything on the spot with incredibly low cost. Sure, we are not there yet, but technologies and concepts are slowly converging to this point.

Here is a detailed talk by Thijs Roumen about the entire concept, the research conducted and the results:

Here is a video focused on the mobile printing process:

They used modified M3D machine which was cut down to more compact size of 9cm in hignt, equipped with a UDOO control PC computer, shoulder strap and a battery. I expect that someone will make simillar open sourced machine soon.
