Designing a 3D printed electronics enclosure

This will be a quick post about the design and 3D printing of a custom enclosure for a temperature logger (see full writeup here) Рa project which has been sitting on my table 90% finished for about a year now. I always find the enclosure to be the most time consuming and least interesting part of any project. As such an unfortunately high number of them stall at this final stage. 3D printing a custom enclosure is a much more interesting and attractive alternative to my usual approach of attacking a jiffy box with a drill and hacksaw.

The box needs to hold a board roughly 90x50mm, have a slot for an SD card, 3 temperature probe input connectors, a DC jack power input, a 16×2 character LCD and 3 pushbuttons. The design was all done in Autodesk Fusion (see my previous post) and printed on my Printrbot 3D printer (see my previous post). There were several iterations and test prints along the way to check sizing and tolerances and to test out some different designs. The final design can be found on my Autodesk account here.

Printrbot 3D Printer

After returning from a trip to the maker faire in San Francisco last year I felt like I needed to get involved and buy myself a 3D printer. After some research I settled on the printrbot simple metal. It seems like a solid mid-entry level printer which is easy to get started with and with fairly good support. I went with the kit form with the heated stage option which costs US$749. All up including shipping it ended up costing me about $1100AUD delivered.

Starting out with CAD – Autodesk Fusion 360

This post is going to cover my first impressions of using Autodesk’s Fusion 360 CAD program from the point of view of someone who is completely new to CAD. ¬†Several months ago I bought myself a 3D printer (a Printrbot Simple – hopefully I’ll do a post on this in the future) partly as an impulse buy, partly because I’ve always been curious about them, and partly as an excuse/reason to learn how to use CAD to design parts.
