I used this project to experiment with TPU air. I’ve had some success, but I can’t get it to bridge for the life of me. I really don’t want to use supports because this stuff is so expensive. Has anyone had luck with it? If not, could we get a model with built in supports so we’re not printing them all the way down to the build plate? TPU supports are terrible to remove to begin with if you let the slicer add them
There is someone on here who made inserts for the two horizontal holes. He pauses the print and inserts the supports. There is a video out there also. I know the file is out there, he has shared it, I just can’t find it. Hopefully someone who has it will get permission to post it and share it here. My first build will be complete (less TPU Air) today and I want to get going with the seat pads.

Thanks! I couldn’t find such a file, but it’s a great idea. I threw something together in CAD and I’m testing a print now.
I just looked at the build guide though. Now I’m confused. The two holes that cause the most trouble look like they have nothing run through them. What is their purpose other than to make the print look bad?

Depending on which cushion you’re printing, someone on here posted that they laid the cushion flat vs vertical, eliminating the bridge altogether…
Is there a version which can be laid flat on a 256mm bed? The options I saw were a two piece print which fits in that volume or a single piece bucket seat which requires a large format printer. I do have a Kobra 3 Max I could use for this, but I’d rather use one of my coreXY machines since this stuff is so floppy to begin with
Yes, the A1 plate is to small to lay flat… I can’t talk my wife into getting one of the H models, I was almost doghouse bound for the P2S….
With this project she sees the good that can be had with one. My 11 yo Son already has raised over $550 for our local food panty selling at Christmas and $220- for his Scout Pack.

I have a Kobra 3 Max as well. I haven’t had a successful cushion print on it so far but that was before I learned about the acceleration changes. I wish you nothing but the best!
The Max is being a workhorse right now, printing left and right parts simultaneously. Definitely cutting down the time… at least it feels like it is. lol

I did do the full sized bucket seat on the max and it came out decent, but I really want to use the foaming stuff and that was with regular TPU. I actually print TPU with the PETG profile. I find it comes out well enough and it’s much faster. Give it a try and see how it turns out

What kind of witchcraft are you dealing in? What printer are you using for this? I’d be willing to deal with a clog just to see what a small test cube would look like…lol
