I am a BIG coffee drinker, I have around 80 oz of coffee a day. Before you go, “Say what?!”, let me tell you only 8 of those oz are caffeinated. The rest are Swiss Water Process decaf.
That said, I do make my version of Bullet Coffee. That’s 8 oz coffee, 1 teaspoon butter, 1/4 teaspoon coconut oil, 1 teaspoon whipping cream. This blend does require using a whipper to emulsify the oil, butter, and cream into the coffee. To ensure that the coffee doesn’t go splashing all over the place, I whip it in a 1 pint Mason Jar.
I make all this coffee in an industrial/office quality Keurig coffee maker. It works well, but the 1 thing it can’t do is get my coffee hot enough. After brewing, the Mason jar goes into the microwave, on high, for 30 seconds, which gets it just right. Of course, the Mason jar gets even hotter. I can pick it up by the threaded rim, but I often would burn a knuckle. Not really dangerous, but not pleasant either.
So, I decided to make myself a 3D printer Mason jar holder. I looked for such a thing previously on thingiverse. I tried a couple of the ones I found, but they didn’t work well. A couple of days ago I decided it was time to design my own.
Here it is in Fusion 360
A couple of views of the actual printed part. It works really well. I didn’t get the thread 100% correct, but it’s good enough to get the job done.
