My odyssey continues! Here's the PCB layout for the battery power regulator. Everything's packed in there pretty closely... we'll see how that works out on my mill, and the eventual assembly step at the end.

Whoops... need to use connector symbols or I don't get the right footprints for my pins. v2 schematic: 😀

My first schematic! It's a simple power regulator for a Li-ion battery.

The exciting saga concludes! The final print is done and the new pepper mill works perfectly. :blobaww:

Green is the best color!

Second test print worked much better. The grippy bit of the crank arm hugs the grinder shaft much better now. (Phrasing? Are we still doing phrasing?)

I think it's time to do the full print! I'll just let it run overnight. Thankfully my trusty Lulzbot isn't that loud, and the cats pretty much just leave it alone.

Test print done! The bottom designed part fits the metal bits perfectly! :blobaww: I love it when I get something right the first time.

This part is Turbo (my cat) approved! :blobcatfingerguns:

The crank arm part (for lack of a better term) needs a slightly tighter fit to the grinder shaft though, so I'll do another round of design/test print.

I'm going to try some smaller test prints first on the current print head though. Only a few hours, shouldn't take that long. =D

Holy cow! It's a 14 hour print with the current silcer settings! :cate:

I normally use a very small print head for ultra-detailed parts, but this is a bigger project. I might need put the stock print head back on. It's much bigger and should hopefully print faster.

After that: design the plastic bits.

Since I'm using an FDM 3D printer, I have to design the parts without any vertical overhangs. It's a bit tricky, but working under constraints adds a fun challenge to the design. =)

Here's the initial draft design. I'm sure I'll have to tweak some stuff after testing fit and movements and such.

First step: make models of the important parts of the metal bits.

I'm using FreeCAD for this. It's a pretty awesome piece of software given the price tag (free), but it does have it's quirks, frustrating limitations, and necessary workarounds. I always wonder if professional CAD tools are hugely better, or only a little bit better.

Holiday staycation project: Fix this broken pepper mill with a my 3D printer!

I don't usually develop things in the open because reasons, but I'll give it a shot this time.

The parts of the pepper mill don't stay together anymore... probably because some plastic bit has snapped. Let's see if I can do better!

Me: I weigh exactly 393.29 jars of peanut butter. =D

No one: That's ridiculous! A jar of peanut butter isn't a standard of measurement.

Me:

I just typed a super long regular expression, ran it against a file, and it matched perfectly the first time!

Damn, now I feel like a rockstar!
