Practical (3D) Printing

Although it is getting better a lot of articles about 3D printers and 3D printing concentrate on the tchotchke factory aspect or the high end metal printers and ignore the simple, utilitarian uses that are a much better example of the impact of this technology. The charging cradle for my…

Queueing Up Tasks

I've managed to keep on top of things for a while but now there are a large number of tasks queueing up again. I'd love to know why project work is so bursty - admittedly my scheduling is fairly ad-hoc but it seems to happen in commercial projects I'm involved…

Parametric PCB Holder

Here is a simple, parametric, PCB holder that you can print out. I've added the object to Thingiverse so you can access it there as well as directly downloading the code from my Git repository. This design is useful in the prototyping stage where you have existing boards that you…

Breadboard Wire Bender Tool

This is a simple tool I made up in OpenSCAD and printed on my Solidoodle 2 printer to solve a fairly common use case for electronics hobbyists. It's all available on Thingiverse. As I mentioned in a previous post using correctly trimmed hookup wires is a great benefit both in…

Some More OpenSCAD Utilities

I seem to be on a bit of an OpenSCAD binge at the moment. Here are two more utility modules I've added to ``` /---------------------------------------------------------------------------- * Defines common constants used throughout the AutoSCAD libraries. ----------------------------------------------------------------------------- ----------------------------------------------------------------------------/ //--- Constants /** The value of Pi */ PI = 3.1415926535897932; /** Printer resolution (in mm) */ RESOLUTION = 0.3;…

Online Equation Solver

Designing 3D objects tends to require a fair amount of algebra, if your skills in this regard are a bit rusty (or you are a little lazy or you want to verify your results) then the Online Equation Solver is the tool for you. This site will take an equation…

OpenSCAD 3D Modeller

If, like me, you are better at manipulating code than manipulating a graphical editor this is going to be a very useful tool when you are creating 3D objects for printing. The OpenSCAD 3D Modeller allows you to describe an object using a language very similar to C or Javascript.…
