Creality Ender 3 V2 ~250

Creality Ender 3 ~200
Guess going for v2 is worth it with silent TMC2208 stepper drivers ?
The V2 Pro looks most appealing to me. TPU printing without any extruder drive modifications.

Hello. Sorry for my mistakes but it’s a Google translation. I have a jd 2140 tractor and got into designing these gears. Only I wanted a manually disengageable support. So my sprockets are these…and the motor mount was found on cults3d and printed in petg. I put a banana lever on each side for rigidity and a pallet to connect them

I cant find v2 pro, for ender 3 v2 to print TPU
This upgrade with
PTFE tube
Should be enough? spare nozzles mix, cleaning kit, hair sprayer spare hotend ?
Somethings else to be aware of ?
For tpu, it would be better to take a dual drive extruder. I have this on my elegoo neptune 2s and a capricorn tuble and prints quite a bit.

Yes that’s it. I’m equipped with that and haven’t had any issues printing TPU.

You might not even need the aluminum replacement parts to get started. Just print this with PLA:
The replacement bowden tube is certainly not required. Although if you do replace it, the Capricorn tubes are the best.

Even if order parts now it will be 2 months till they arive so plenty of time to try stock and PLA upgrade. With direct extruder bowden tube is not required?
It says that PLA/TPU/PETG is supported so theoretically no upgrade is needed but in practice its not good?
Essentially correct about the bowden tube.
The Ender 3 has always said it supports TPU, but the problem is the TPU often bunches up between the drive gear and the entrance to the bowden tube. The extruder plate on thingiverse or the aluminum parts on aliexpress fix that issue by reducing the gap essentially.

Very good price. Yes the noise is annoying. I print in the basement because of the noise and the smell.

That’s very cool, I am going to hang this pic on my shop wall! Love the blue colour.
The gears may squawk a little during run in, dry silicone lube spray works great.

Thank you for the gear data, I also agree this project needs an XXXL large gear.

Everything on your farm will now be fixed with custom plastic parts! 3d printers are great for the imagination.
Here is a off topic side project I dreamt up with the printer,
All those little custom ideas start appearing overnight.

Yes it was squeaky at first. I put a water-based lubricant and no more noise. It’s a nice blue, in a John Deere.

Would someone be interested on printing these gears and motor holder for sale? Costs? I don’t have printer myself or know anyone who does. Or can some recommend commercial printer in Europe?

I see that you are from Finland as well, so I could give you some helping hand. Haven’t calculated the exact cost, but I could do that.
I was about to ask to get the Tension brace mirrored, but realized that I can do that myself in the slicer. I’m using PrusaSlicer, but would expect same feature exising in all slicers. This is just a hint, if you are not able to fit things in default orientation.
