GraphSCAD Nodal Editor for OpenSCAD

Dimitri Kolovitz developed GraphSCAD nodal editor for OpenSCAD scripts. It gives an interesting new way of working in this environment with powerful features.

Here is a demonstration of basic workflow and features:

At this time it is still a beta, but it look promising.

gDraw Software that Converts 2D Drawing into G-Code

Niklas Roy developed gDraw software that enables you to draw in 2D and then export it as 3D printable g-code.

In this example he used it to create simple Christmas card:

There are several similar projects, like this one:

Christoph 3D Printes a Brushless Motor to Power his Flying Wing

Christoph Laimer designed and made a very functional DC brushless electric motor.

Here is a test of his 3d printed brushless motor, it explodes above 30000 RPM:

Project homepage with data and files:


He used this motor on a DIY RC flying wing with success. He even developed and 3d printed the propeller.

Here is a link for the propeller page.

DIY Filament Dryer and Cleaner Made with Hairdryer and Sponge

Stanciu Alexandru developed a simple DIY filament dryer and cleaner. The heat for drying is provided by simple hairdryer and cleaning module uses common sponge.

DIY Glass FDM 3D Printer by Stefanie Pender

Stefanie Pender made a glass FDM machine which extrudes molten glass guided by an industrial robotic arm. Glass is melted by oxygen/propane welding torch.  She achieves simple geometric forms, but she gets A for effort and coolness in my book.

Printer working:

Here is the glass "filament" extruder:

Dtto 3D Printable Modular Open Sourced Transformer Robot

Dtto robot is just cool! See it here in the video presentation:

Project description:
The Dtto v1.0 Robot is a modular transformable robot designed to be versatile, flexible and self-reconfigurable. The idea of modular robots is that they can adopt any shape they want, by changing the position and the connection of their modules.

This robot is aimed for research on modular self-reconfigurable robots and educational purposes. It is designed to allow multiple modules to communicate, mechanically connect and disconnect and to work collaboratively in the locomotion, self-reconfigurability and efficient movement.

The versatility of the robot will allow it, in the future, to be able to perform rescue operations, exploration of unknown environments and space exploration.

In future works, the modules will have built in camera, ultra-sound sensor, gyroscope, accelerometer, magnetometer… The possibilities are endless.

Dtto key features:
  • Small and self-contained robot
  • Fully 3D printable
  • Self-reconfiguration capabilities
  • Bluetooth + Radio communication
  • Multiple locomotion modes (snake, wheel, walker...)
  • Rechargable batteries
  • Simulation model validated
  • Cheap modules (<55 USD)
  • Open Source Hardware and Software

Dtto is made from modules:

Tom Stanton 3D Prints his RC Flying Wing

Tom Stanton show us his trials and tribulations to get a 3d printed flying wing RC aircraft in the air. Interesting watch if you are into this hobby.

Here is his first video where he goes into design and basic parts printing:

Here is the fully 3d printed flying wing being developed and tested:

The aircraft was printed from clear PLA filament with a 0,4mm nozzle at 220 degree Celsius to maximise the layer strength. Weight of the aircraft was 730g.

Simple Technique to Acetone Polish your ABS Prints

DIY Perks YT channel published this video with very simple and effective way to acetone vapor polish ABS parts with a simple glass container. Finished parts look very good and smooth.

Here is a tutorial video:

This technique uses the fact that acetone vapors are heavier then air and they fall down in a container. Water is used to create an air tight seal.

Make your own 3D printable handheld tractor beam emitter

Asier Marzo, a researcher at Bristol University, made this amazing project where you can make your own DIY handheld tractor beam. Currently it holds only small objects like liquid droplets or small insects.
It is Arduino controlled, cheap to make and uses ultrasonic sound emitters to produce the tractor field. You can make it for some 70 USD and with basic electronics skills. Ideal educational or school science project.

Here is a video of the device in action with some construction instructions:

It is like simplified home made sonic screwdriver from Doctor Who :-) Here you can see a small red liquid droplet floating in 3d printed sphere that holds ultrasonic transducers.

Step-by-step build guide with all the files and the code:


Detailed research paper with the science behind it and device design:


You can also find different type of the same device developed by the same author. It is a horizontal 3d printedplate array of ultrasonic emitters that make small objects levitate.
