3D Printing Are there effective 3D printable ejection baffles?

Are there effective 3D printable ejection baffles? If so, where can I get the STLs. Would PLA+ be good enough to use for that?

For low powered rocketry BTW.

PLA is not that resistant to heat. I use PETG for my baffles up to a BT-60 size.

Pretty sure this is the one I use and modify:

Weight is the biggest issue - try to make it as light as possible - IE only 1 parameter...

Made this for 2.5" PSII tubes.

BT80 in the files for a kit here.

PETG; and they work well.

These I just designed a couple of days ago. They are baffle bulkheads for a LOC 3" coupler with centered holes for 1/4 eyebolts. They are a chucky 6.3mm thick. I printed mine with 100% infill in PETG. You can resize/remix as you see fit. They should last for a good while. These have not been tested yet except for fitment.

That's the one I used in my Betamax builder's kit. It works great!

sorry... just saw this.

I designed and printed some a while back but have not tested them. Secret is to design something that does not require supports...

Hmm, post the file.

PETG is better, but not that much better. ABS is better, and ASA is about the same or maybe bit better.
