What about 3D printed tees?

[bb1632]

Has anyone modeled the #1 birtee? I lose those little buggers like crazy!

How tall are Birtee #2 and #3?

I don't know what # Birtee this thing is like. I guesstamated proportions from a picture on the web. This one is hard to print. The tee in post#65 is easy to print and is more durable.

PLA test print - GizmoGeeks TPU - NinjaTek NinjaFlex

NinjaFlex crazy flexible compared to GG-TPU

[Jerome]

I got the NinjaFlex loaded and first 6 layers down at 10mm/sec. Monoprice mini select V2 has a very short bowden tube and tiny gaps in the feeder. Its going to be slow but I think it will work.
[edit] 10mm/sec and 15mm/sec printed fine. 20mm/sec bunched/jammed in the feeder.


[edit2] OK, so I broke my driver shaft testing the NinjaFlex tee (41 drives and counting...). To start the re-shaft of my driver I put the PXG(not bragging..but :-) ) sleeve with the broken shaft on the wood stove and opened the vents up. The basement, where I'm allowed to work, got hot(75F+) and all NinjaFlex prints failed.


Moral of the story.1:
Build a shop away from where your wife lives.
Moral of the story.2:
If you want to print NinjaFlex on a cheap bowden printer, keep the room temp down.

Printed one in cheap TPU, after ~20 shots it is still in good shape. The wall of this one is thick at the bottom and taper thinner to the top. That, the "twist" and good geometry might make this a acceptable non-ninjaflex birdTee like option.

It’s super hard to even get loaded to print lol. I have an artillery v4 and I’m putting a genuine bondtec direct drive in tomorrow as the Chinese direct drive in the stock config took me hours to feed the ninjaflex and gives me issues going from abs to even tpu

[Jerome]

I'd love to try foaming TPU but this is getting out of hand LOL.

I like the look of the previous one better
although I think this new design will print easier

[Jnc10]

the ninjaflex is much harder to print on a bowden drive. direct drive is easier

[Jerome]

The OCD in me could not take some of the less than optimal geometry in my attempt at the bird tee. I'm new to modeling, only making crude 3d place holders for past software projects during development. Here is a cleaner bird tee like attempt:

yeah, messed up and ordered armadillo. I was able to cancel and get blue NinjaFlex 500g for $35... I think :-p

[Jnc10]

the only ninjaflex I saw at $26 was the armadillo which is not as flexible. Is that what you bought? would love the hear how it works out

[leibin]

Damn, mine was almost $50 for .5kg on Amazon! Lol, so less than .50 a tee. Funny thing was I thought it was for 1kg. When it arrived, I had to do a double check on the order. It’s a pia to print compared to any other filament I have, but always fun to tinker with printing.

I also had success printing this with sainsmart tpu

[Jerome]

500g ninjaflex on Amazon is ~$28 with tax(just ordered after watching some reviews :-)).
1 "BirdTee" above is less than 5g, so ~$0.28 a tee.
