Made the Dummy 13 model at 150% [LINK]. This is basically an advanced plastic model kit (sort of like Tamiya or Revell) except it supposed to snap in place. You will need to sand down a lot of parts. Highly recommended to print the parts individually and upright. And eh, I will NOT ever make this model again, my fingers hurt.

Prusa have gone core-xy now too. They have the "Core One" (for Bambu moneys!), and will soon offer a 4s-Core conversion kit.

Ok then, could the core 1 print glass filled polypropylene

No idea. Maybe check with Josef Prusa?

It doesn't have an actual chamber heater, but it should be able to maintain temperature enough to combat shrinking. You'll need a hardened nozzle as the brass will get blown out in short order.

Well i knew bout the nozzle so yeY the mk4s can print normal polypropylene

The more I hear about the Elegoo Centauri Carbon the more I like it. I may have to order one.

Modiefied the horizontal phone stand (linky) to support vertical positioning, this time with the 3D-pen.
I know it will not win any beauty awards but it gets the job done. It goobs out the plastic at whatever the rate & temp you set. Then you just gotta think about orientation and start doing lines
It holds 3 pieces of an EK kit. Now I can set the phone vertical without it topping over. And that was the goal. However...I'll probably will add a bit of extra stuff to reduce the angle. It works with the 24FE but not with the A52s.

I wasn't sure if it would stick to the surface but it did immediately. I could use a heat gun to smooth it out but I'll add that on the "to do list"

He reminds me of Zer0, the BL3 version.

It reminds me of the Micronauts toys I used to play with as a kid

I pre-ordered the Elegoo Centauri Carbon. Just couldn't resist. Unfortunately, the current batch (after Feb 17, 2:32 PM) has an estimated ship date of Jun 30,.......ouch.

My niece liked Dave the dummy so much she wanted one too but only a female variant.

Still need to print the hair

Interesting, so I’m guessing most of the parts are the same for the female version.

Yep, you can mix and match. I'm using 3 different models but all fit the original dummy-13.
The most basic one just rounds most limbs (armor) pieces, the second model adds a bust with..shapes, and the third model adds a face & hair piece.

 

[SN2716057]

And done! Hopefully 4ever with this model.

Not the best; hip & upper leg don't fit properly, and the arms are still a pita. But she loves it, and in the end that's good enough for me.

PS: I have printed spare parts

What about the accessories

BTW, anyone have any idea if the stateside tariffs will effect the Elegoo Centauri Carbon prices? I pre-ordered but a pre-order isn't a done deal. Just wondering if there will be some surprises.

I gave her the extra hands that came with the kit. But nothing extra for now.

Edit: Shiii...now my mom wants one too

That's how print farms get their start,...

Now about those accessories

How about a scaled down version of one of those robot dogs:

Finished my hot wheels display

Finally got motivated to rebuild my Ender3 V2.
My dual-motor Z-axis kit arrived few days ago, and I re-printed my direct-drive assembly for BMG extruder.
Replaced the hotend as well, cause the old one got killed with some really bad "experimental" PETG batch.
Unfortunately the thermistor and heater wiring is a bit too short. Gonna solder-on an extension today and put it all together.

“The Ship of Theseus“ comes to mind looking at your Ender 3 V2.

I was thinking about adding a second lead screw as well because the gantry design practically requires it IMO. You can tighten thinks up but there is still some play in it.

80% of Ender 3v2 become some sort of Ship of Theseus. I'm going to start modding mine to be my PLA dedicated machine since my others are going to be meant to work with either shrink prone materials or more engineering focused ones.

Welcome to my dungeon #2.
Had to move some stuff to my second office, including printers. It isn't my primary workspace, and that's why it looks relatively clean
So, Ender 3 v2 finally done. Loaded up my spare spool of wet PETG to run some calibration tests.

Also, that K1C ain't mine, but I've been "fixing the living $#it out of it" while the owner is away

 

[Octavean]

I am still amused with the Creality Ender 3 v2 but I'm eager to get a smore reliable Core XY newness,.... The wait for the Elegoo Centauri Carbon is considerable (Jun 30). Every now and again though I think, "Just order a Bambu Lab X1C, P1S (with AMS) or Creality Creality K2 Plus (combo) and have it in like a week or so. Even less time if my local Microcenter has them in stock and I think they do. It just seems prudent to wait it out though. ~$300 vs up to ~$1500. Yikes. If the Elegoo Centauri Carbon gets me ~90% of the others at ~$300 it's a game changer IMO.

Had a little project today, which kinda is a perfect demonstration of what 3D printing is all about.
One of my clients got a side hustle as a DJ, which motivated him to fully refurbish his Technics RP-DJ1210 headphones.
I actually liked these headphones so much, that I bought a pair for myself for really cheap (though in even rougher shape than my client's).
Installing new ear cushions was a breeze, headband was real pain in the ass (had to disassemble the whole thing and desolder speaker wires). But the hardest part were those pesky wire covers on the folding mechanism. The old ones crumbled and fell off a long time ago, and replacement parts were nowhere to be found. Even Aliexpress told me to bugger off with stupid search requests
So, I spent 30 minutes registering and installing Fusion360 (gotta get off this thing, cause it's getting very annoying, but that's the only tool I'm familiar with), another 10 minutes designing a rough copy of the cover, and another 20 minutes printing on K1.
The end result:




As a bonus: PETG is more flexible, so taking these covers off and putting them on doesn't break those tiny internal clips.

I was thinking about adding a second lead screw as well because the gantry design practically requires it IMO. You can tighten thinks up but there is still some play in it.

That's definitely the best upgrade for ender3. The branded upgrade kit only cost me $23, but you can make it even cheaper: all structural parts have printable equivalents, so all you really need is one stepper motor, one 8mm lead screw(same as the one installed), and one nut for it.
I didn't even mess with manual gantry leveling - just did a quick hotbed adjustment, re-calibrated z-offset, rebuilt the mesh, and got a very respectable first layer on the very first try... and that's with dusty print surface and very-very wet PETG (ended up with very-very matte and very-very hairy Raspberry Pi case).

The wait for the Elegoo Centauri Carbon is considerable (Jun 30). Every now and again though I think, "Just order a Bambu Lab X1C, P1S (with AMS) or Creality Creality K2 Plus (combo) and have it in like a week or so.

Or you can just get an Elegoo Centauri non-carbon. It's even cheaper... at $199!!! and the only difference is doors and lack of camera. TBH, for personal use camera and all the "AI defect detection" gimmicks are useless. And enclosure is only critical for some niche or specific types of filament. Regular PETG and PLA prints just fine without it.
BTW, looks like a very decent printer. Pretty much a 1 to 1 copy of K1C. Even firmware is the same castrated Klipper with Elegoo skin(probably can be unlocked to full Klipper just like Creality).
Just found one in stock locally, and it's $50 cheaper than the cheapest Creality K1 in Ukraine. I guess I'm getting that one instead(I'll just ask my bud to cut doors out of plexi on his CNC, and stick an old webcam in it). Not sure if someone is selling their review sample or something fishy is going on, but I'll try to order it tomorrow. Listed "in stock".
