Accidental 3d printing art

 Every once and a while a print goes wrong and turns into a piece of art unto itself.

This is the print I'm trying to slice and print.  Nothing too crazy about it, except there isn't a lot of bed adhesion.  Add to that PETG's tendency to clump and string when not perfectly dry and you've got a recipe for a failed print.

The print looked kinda neat once I took it off the plate though.

Quick recap of Christmas Tree Project

I'll never make any money as a blogger.  Its never my goal or objective mind you, but it's abundantly clear to me that I could never make a living as a writer.  I just don't do it consistently enough.   These posts are mostly to gather and record my thoughts so I can remember later in life.

So I used NeoPixels to light my Christmas tree a 2022.  I put a post up about it when I was getting started and never followed up.  A lot like my photography posts.  Oh well.  The original post: 

Trying to NeoPixel my Christmas tree part 1

So I started to get it working quite well and had the tree wired up for the season.  I never went on to build the web front end so I could change the lights remotely.  Maybe in a future try.  

I even had enough lights left over to wire the tree in our office:

In both cases I'm running the color wheel code example from the MIT project.  I did make some that did alternate pattersn - like alternating red and green, sparkle/flashes, even did some hand mapping to do it by rows.  All the code is in my XmasTreeLights github repo.  In general it would be better to start with the Matt Parker code, the MIT code or AdaFruit's neopixel tutorials. 

BBr2 from Michael Baddeley's patreon on my new BambuLabs P1S

For last christmas, on a whim I decided to print a BBr2 (BaByR2) from a patreon I subscribe to: Michael Baddeley (I'm also printing a full size R2, more on that in another post).

So I sold all my camera gear and used the money to buy a BambuLabs P1S with AMS filament changer.  It is an excellent printer.  If you can afford one, get one.  Even the P1P would be a great printer to get.  Speed and quality in a single package that isn't "Prusa" expensive. 

The body came out great on the first try.

The dome prints very well without supports. 

 Printed two legs, some tires and a center foot and it was time to assemble. 

It's a very easy print and pretty easy to assemble with some screws and superglue.  It takes 3 servo motors and somethign to control them.  Since this was my first attempt I went simple with a FlySky FS-I6 from amazon. 

I initially printed the oversized "cartoonish" dome.  I just picked the default dome from the file list.  After gluing and assembling I wired it up to an adafruit crickit to test the dome.  Adafruit makes it super easy to control servos, especially when you're just testing things out. 

I later found the holiday themed dome.  I had some red filament laying around from a previous project idea so it seems a perfect time to test out the AMS.  Turned out excellent!  I bought some "metalic" paint markers from a craft store and started coloring the white in.  

*EDIT/UPDATE* - found the time lapse footage for the Santa hat print:

The AMS does create a lot of waste with the filament changes however:

Later I went back and printed a classic dome in gray PLA and colored it in (still have some more to do)

Super fun project, glad I spent the time on it. Wish I had better hand/eye coordination to paint it better.

3d printed Chewbacca Bowcaster

 

Catching up on my posting - last year I printed myself a Bowcaster for my Chewbacca costume.

The costume was pretty simple.  It started with a onesie I bought at target a while back on a whim.  I added the talking Chewbacca mask and it was pretty much done.  All I needed was the bowcaster.

I found some STLs on Etsy Designed by MysteryMakersStudio - Custom digital DIY Bowcaster with stand stl file(digital download) and I was off and running.   As an aside, Marko Makaj, the designer has a reasonably well priced patreon  as well if you want more than just one model.  It's important to note it's makers plural.

Anyway was off and printing on my new Ender-3 Max Neo 3D Printer.  I don't think I mentioned that yet - should probably post about it too.   I bought it because I wanted the large build area 300x300 and the NEO line with the SonicPad was supposed to be a game changer.  Meh. It prints.

The parts all came out pretty good.

Next came all the gluing.  So. Much. Gluing.   It went together pretty well.  The polarizers (the balls on the end) are a bit heavy for how thick the actual bows are.  I managed drop it and break them off more than once.

One of the tricks I tried in this build was to use UV Resin from my resin printer to fill in the layer lines.  It's very effective but smells pretty bad when you cure it with the UV flashlight. 

fully assembled! (It did drive me to drink.  A little Smith and Cross rum there on the table).

One of the resin printed lenses cracked when I took it off the plate.  I left it as is for "authentic battle damage!"

Primed.  I later used rattle-can gloss black and then some Rub and Buff silver to to make it look metalic.  Came out good enough for me.  

Lots of lessons learned, could do a lot better if I did it all over again.  Now I just need a place to store this bad boy.
