Been playing with a few different coin ideas, another one I’ve got in progress lights up when squeezed in the middle. This one was meant to be a sort of hammered finish, but the spheres i subtracted to produce the surface should have been a little larger.

We’re heading into the last weekend of the challenge! How are people feeling? I personally have a bunch that are within striking distance of being finished, but aren’t quiiiiite there yet.

My current vibes are that there’s nothing quite like turning a project right before midnight, errors and all!

@torchedguitar and I are trying to squeeze in some last minute electronics ones with those cool boards y’all ordered! Mine isn’t functional, but will hopefully look cool

I’m still working on some final pieces. Confirming - this ends at 11:59pm tomorrow, not in 4-ish hours, right?
That’s right, you have until the end of the month!

I’m super excited about my very basic electronics chip and that this gave me a low stakes opportunity to work on my soldering skills

Please make sure you fill out the submission form before midnight if you have any changes!
I’ll come by tomorrow and photograph the entries and start a thread here with a voting link.
Reposting the entry form for anyone else like me that may have lost track of that (maybe just me)
By the way, I trust y’all will stop work at midnight, but if you need to deliver your finished chips a bit later (like tomorrow morning), that’s fine. If you have a finished chip that you can’t deliver before tomorrow afternoon, take a picture and post it here and let me know when it’ll arrive.

I just made a list of firsts/things I learned as part of this contest. I’m sure this is incomplete:
- 3D Printing
- M600 filament changes (thanks @flowmage) to print in 7 colors on a printer with 4 working extruders
- Tell PrusaSlicer the printer has more extruders, then post-process the .gcode to change Tn+1 to Tn + M600
- Metal
- Carpet tape fixturing (thanks @Kenneth for convincing me to keep trying)
- Max .010" cut depth with 1/8" end mill to stop breaking free
- First time milling brass
- Jeweler’s saw is better than filing to get into sharp corners
- Wood
- First time using the Laguna iQ
- Fixturing using dowels as locators - rebore the fixture each session
- Milling with 1mm end mills isn’t hopeless! Broke less than half of the package I bought
- First time working with multiple woods in same project
- First trip to Woodcraft

Lovely list to read, amazing, ya did real good! I look forward to seeing everyone’s results and any documentation on everyone’s process and results. Thanks for yours. I agree that these community challenges are great. Although I didn’t participate in this one, I enjoyed the earlier 2’x2’ challenge and learned lots then too.
