Wiki says: Slic3r is free software 3D slicing engine for 3D printers. It generates G-code from 3D CAD files (STL or OBJ). Once finished, an appropriate G-code file for the production of the 3D modeled part or object is sent to the 3D printer for the manufacturing of a physical object. As of 2013, about half of the 3D printers tested by Make Magazine supported Slic3r.
The Prusa company maintains an advanced fork named Prusa Slicer (originaly known as Sli3er PE) optimized for the Prusa i3 series.
I was asked to print a replacement for a broken part of an elevator. I don't know where exactly this piece fits on actual elevator, but it seems to be a cover of an emergency telephone speaker.
Originally I wanted to do it my traditional way. First scan the piece using ordinary 2D scanner. Then trace outlines in Inkcape to get vector paths. Export paths to Openscad and there use several extrusions, differences, joins and other operations to create a model.
Before christmas 2017 we had LDTPardubice meeting and I wanted to bring there some traditional czech christmas sweets, but in original shape. In shape of the LDTPardubice logo. In the same time, my girlfriend was visiting her friends in Soria - Spain and had similar idea: czech sweets in shape of the Soria horse.
Lightweight watchband for original Pebble watch, but also customizable to adapt any standard watchband widths. Customization can be done by changing parameters in OpenScad source file, ore using Thingiverse's Customizer.
Band si designed to print with links already assabled together, so no postprocessing needed. You just connect band to watch using their standart axis.
I built my own 3D printer based on open hardware RepRap printer Rebelix X2, but improved by my own design customizations. Printer consists of plastic parts made by similar 3D printer (I used 3D printers at Czech Technical University), standard aluminium profiles, stainless steel rods and bunch of nuts and screws.
