For our garage door motor we have a remote control, but when changing the battery, the plastic case broke. First impulse: Let’s 3D-print a replacement. Thinketh me: Wouldn’t it be much cooler if it was made from wood? So I turned it into a milling job, using a piece of oak board as a basis. And what can I say? The result is the coolest garage remote I can imagine 
- but judge yourself:
I created the case using Windows 3D Builder (I’d say it is about the limit in complexity this program can handle…), imported it into Fusion 360 as a Mesh and created for the inner side
- A pocket clearing with a 6mm wood milling bit (https://hc-maschinentechnik.de/index.php?a=4249&lang=eng)
- Another pocket clearing with the Snapmaker 1-flute 1.5 mm bit for finer details
- A pencil finishing with the Grove V-bit from Snapmaker for some very tiny details
And then for the outer side and the knob
- A roughing with the 6mm bit
- A contour finishing with the Snapmaker 3.175 mm ball end bit
Gave it a bit of sanding and oiling, done!
Some learnings:
- Invest in quality! The 6mm bit is super fast and super precise - no comparison to the Snapmaker bits, where the machine really struggled. To be fair, the Snapmaker bits are cheaper by an order of magnitude.
- Do a finishing path. I thought I can skip it for the key ring holder, but had to work it out with a knife a bit. I could have avoided this.
- Think well about how to fixate the work pieces - I had to redo the job, because I was too stupid.
- A two side milling is difficult to align - I still need to think about more precise ways to do this. It is not an issue with this project, but alignment was off by ~0.3 mm, and that’s already a lot in places.
- And of course: It is a good idea not to do everything in 3D printing - the other workloads are also fun!
