This application visualizes Gcodes and simulates a real 3D print. GCode Simulator recognizes the movements and print speeds and can simulate the print in realtime, but you can also speed-up the prints (fast forward). Each layer is painted in a different colour to see how a layer overlaps with the layer below. In addition to the top level view it also renders a front and side view of the object. GCodeSimulator let you to check how your print should turn out, making it easier to spot errors ...

BOLTS - a open standard parts library for open source CAD applications

The aim of BOLTS (acronym for: BOLTS is a Open Library for Technical Specifications) is to build a free and open-source standard parts library for CAD applications. It does so by providing a common database that can be utilized by different CAD applications.

Currently supports OpenSCAD and FreeCAD.

There is also a development blog.

"kokopelli is an open-source tool for computer-aided design and manufacturing (CAD/CAM).

It uses Python as a hardware description language for solid models. A set of core libraries define common shapes and transforms, but users are free to extend their designs with their own definitions."

"3DPrintMi combines the minimalistic, open frame style of the Printrbot/Wallace with the fixed Y Gantry system of the Mendel. The printed parts are designed to be produced rapidly, efficiently and assembled easily. A primary goal for this printer was to incorporate the maximum number of printed parts, thus enabling self replication. Built from the ground up, this RepRap requires very little tooling and does not need specially made parts (e.g. lasercut pieces) for it to function."...
