A couple of weeks ago I started to make a tiny audio system for our cooler. In my previous blogpost I described all the audio components that I chose for this project. I wanted the components to be small since I didn’t want to waste too much space in the cooler. With the audio components in hand I could design other parts for the audio system. I needed an enclosure for most of the audio components and a simple console to operate the audio. The parts were 3d printed with my Hephestos 2.
The last couple of weeks I’ve been busy mastering 3D modeling programs and bringing my creations to life with my Hephestos 3D printer. In this entry I’ll share some of my creations and how they were made. For 3D modeling I started with OpenSCAD in the beginning of this year and later started using FreeCAD. The reason for using FreeCAD is that with more complex design in OpenSCAD it is easy for me to get lost in a large script. Yes, the learning curve of FreeCAD is steep but eventually it’s easier for me to create more complex models in this program than in OpenSCAD. For simpler models I still like OpenSCAD better.
I have a MK194 radio kit from Velleman and turned it into a radio some time ago. The radio looks pretty cool with all the electronic components visible but the wooden case was awful. I therefore decided to build a new case for it. Of course I want to use my Hephestos 2 printer from BQ to make this case.
First I designed a case in FreeCAD. I use FreeCAD for a couple of weeks now, together with OpenSCAD, but this is the first design with multiple parts that I create with it. After several iterations I finally decided to have a design consisting of three parts. A box, a support plate for the radio PCB and a lid. The radio fits into the support and the lid which are then screwed onto the box.
The box is by far the biggest 3D print that I made with the Hephestos. It took the printer almost seven! hours to print it. Luckily it came of fine the first time. Both the lid and the support plate were printed in less than an hour each.
While making my projects like the Darth Vader chest box 2.0 I use the local fablab a lot, especially the laser cutter and the 3D printer. It was a bit boring to wait for the 3D print to finish (laser cutting is typically much faster) with not much else to do at the fablab. I therefore decided to buy my own 3D printer. I choose for the BQ Hephestos 2, a sturdy Prusa i3 all metal printer that comes in a kit.
