I also got some regular and HT blank OpenPrintTags so tomorrow I can start tagging non-NFC spools tomorrow. And also weighing my partially used NFC spools so they’re stored accurately in the database. Fun times.

In today’s #3dprinting shenanigans, I installed the Prusa NFC adapter. Of course I immediately had to try it out on a NFC spool and it worked like a charm. Feels a bit magical though it is trivial.
Final bit was to replace my existing spool holder with the newer injection-molded model just so I could use something like this: https://www.printables.com/model/1846179-custom-spoolholder-cap-with-integrated-hygrometer or a silly design.

No major projects involved but today I’ve already used 7 different filaments: 2x TPU, 4x PLA and 1x PETG. Another great day😆
Marlin Simulator now provides the printer visualization as a webcam. Great for working on firmware and host development at the same time.
Run MarlinSimUI locally, Mainsail / @octoprint in Docker, set up and go!
Skills included with Marlin.
Always a good day when I find an excuse to print some parts using PC Carbon Fiber. They always come out looking so freakin' awsome on the C1+G2.
I use these fancy vacuum bags for storing my 3D printing filament. They came with a cute little USB-C vacuum pump that technically does its job. It just takes what feels like 10–15 minutes per bag.
So I bought an adapter for my Dyson vacuum cleaner. Does the same job in under 10 seconds. 😁
Apparently, the solution to filament storage was never about technology. It was just about adding more horsepower.
Amazing Space Age things are happening as the drudgery of doting on details is quickly giving way to pure fun, exploration, and punctuated evolution!

I needed a case for an IOT device I created. I tried a “chocolate brown” woodfill (top in photo) then tried a Notcua brown PLA and although both were fine they both caught a color cast in the intended location.
In a first for me I applied a “kona” stain to the woodfill print using a simple brush. Didn’t bother with any prep but it turned out great and just what I wanted. The only special step was to use a paper towel to dab up excess stain since it naturally doesn’t sink in much.
#3Dprinting
I’m finally going to jump into the 3D printing game.
Any recommendations for a first time printer?
My main reason to want to get into it is to start printing model spaceships, as want to get back into model building and painting again.
A solid week of 3D printer time later, forty two pieces of a custom stair railing are ready to be assembled with Gloop, dowels, and a furring strip down the center.
Why? Because the linear, angular stair railing currently in the L-shaped stairway up to my condo is boring, and I want a smooth curve!
If you like using Mainsail as your print host you will be able to do that with Marlin a lot more easily on the next update. The key is a little connector called Serial2Moon.
Soldered a battery connector to my esp32-c5 board today with a customized case that I modified with battery clips. The seeed has a built-in GPIO connection and voltage divider for reading the level. Had to peek at arduino sources to figure out the right attenuation level, seems to be working from esp-hal in rust. I want to show the battery level on the web pages and do a safe shutdown before the battery gets too depleted.
Still prototyping; I want to add a bigger antenna, SD card adapter and a GPS module. Placement is tricky!
New in the Simulator….

#3DPrinting #OpenSource
We're operating in the red, but busier than ever!
It's never been a more compelling time to choose an optimized single-board air-gapped #OpenSource solution for your #3DPrinting or other motion system. We've got you covered with no compromises and much more ahead.
Prusa have continued to breach their own GPLv3 license. I have written up details which include their reasoning, and why this matters, into a blogpost:
Danb BlogPrusa Breach Their Own GPLv3 License for Over a Week · Danb Blog9 days ago Prusa started distributing
Firmware 7.0.0 for their printers, which was followed up by Firmware 8.0.0 two days ago.
As of writing, the latest published sources are for Firmware 6.9.2.
I had a problem. I used #3dPrinting to make a tool. I no longer had a problem!
These #shelly pro 1 relays were in a tight box and I wanted to make a wired connection to my switch. I couldn’t get the RJ45 plug to line up without messing with the other wiring.
So, I fired up #OpenSCAD, grabbed my calipers, and had a design in 15 minutes. 10 minutes of printing and my tool worked the first time.
The first cable w/o the tool? 15 minutes.
Cables 2-5? 15 minutes total.
Interesting! I wonder if you could mount this on an axis of a 3d printer?
Most printers work on dead reckoning (is that the right term?): they find zero and assume their location based on motor rotation. That requires accurate motion systems, which is great… until it isn’t.
This type of system could open up all sorts of alternate motion systems because we’d have feedback on print head location as well as motion system correction.

If you regularly use a knife for #craft #3dprinting, #parcels .. whatever.. and always need a sharp blade you can pick up a #knife that holds a #60 #scalpel blade.
Just be sure to pick up the stainless steel blades (carbon steel is common).
Of course it goes without saying these are very, very sharp. The handle does not lock. Don't get one if you regularly cut yourself.
The size 60 blade are for autopsies.
I also have a size 23 handle, I picked up 100 blades for $15.
O.D.I.N. miniatures just got cheaper: every set, a man and a woman in 28 mm, is now €3.90 as STL or from €12.90 printed in resin.
Until Friday, 23 October, code ODINSTART takes another 10 % off, and three sets or more save 15 % until 8 November. Printed sets ship within Germany only. Shop: odinarsenal.etsy.com
The figures were designed with AI and finished by hand.
O.D.I.N.Miniatures for the O.D.I.N. tabletop RPGO.D.I.N. miniatures: every subclass as an STL file to print yourself or as a printed figure, with or without base, available on Etsy.

Reminder: #3dPrinting buildings is a scam and a grift.
It makes no sense: the part that is printed is the cheap/easy part. Once you figure in things like insulation and services, you’re left with an energy and space inefficient structure that costs loads.
Dude in the article talks about $220 sq/ft and says it’s comparable costs to the region. Thats true - home construction in that price range in FL but he is building a *fucking barn*.

Creality are also starting to use Prusa's non-open-source "Open Community License".
I've called them out on it early:

Let's see of they respond better than Prusa!
Possibly a long shot but does anyone know how to remove the extruder from a Flashforge Adventurer 5M so I can fix the connectors for the front panel fan? I do not want to watch a 30 minute Youtube video, I just need to know what screws etc to disconnect, but everything online is a bloody video, which is not just annoying, it's really hard to see what's being done while someone's fiddling around with the stuff. #3Dprinter #flashforge #3dprinting
