This was built from plans in the Apogee Peak of Flight Newsletter #523.

Nice

Was this scratch built? Nice job done it. I’ll have to look up the newsletter and check this one out.

Built from plans in the newsletter. IIRC there are links to 3D parts and decals from third party vendors. Cut my own clear plastic fins.

Gathering parts... Got the .08 inch thick fins cut on Glowforge... Got the baffle weight down to 10 grams, but it's far to weak. Had many parts already. Having "issues" w the grid fins as others have mentioned. Kuririn, can I ask what settings you used to make your fins? They look great!

BTW, Apogee has combined everything needed in 1 file from

Thank you Apogee!

I don't have a 3D printer yet so I ordered the grid fins, legs and capsule from a third party vendor.

You would really dig on a 3d printer! Do we need to double-dog dare you!!!

I used the plans from Apogee to build the pair of them: Falcon and Falcon Heavy.
The heavy was flown on D12-5/C6-3 with successfull separation and recovery on the second try.

They look great! Did you 3d print your rid fins?

 

[matthiasabele]

Thanks.
I cutted them as through-the-wall fins with a CNC 3040 from polycarbonate. I messed them a bit during painting and glueing. For the Starship I am working on, I will add them on the very end after painting.

Just saw you asked about the grid fins...sorry for my answer to a question never asked.

I've printed them on an Anycubic Mega X using my regular settings for ABS, but a 0.2 mm nozzle and a layer height of 0.1 mm.
In the end I reworked them piece by piece using some sandpaper an a scalpel.
