Now that I have flight tested the thing, here is a link to a 1-piece low profile shroud for an 808 camera. Fits a 4" airframe and stayed on at Mach 1.1

https://www.thingiverse.com/thing:3626341

I have it on my list to do a 3" version, but haven't got there yet.
I love the 808 #16 cameras. I was lucky to get the cameras before all the cheap Imitations hit the market.
I would like to order a 4" and a 3" color bright orange.
thanks

Hello Chums,
Here's my fin can program. It's a work in progress.
What's different about this?
Height of fin can be set at Start of Leading Edge, End of LE, Start of Trailing Edge, End of TE. This gives you "curved ish" tips. The limitation is that the "hull" function used for the fins effectively drapes a blanket over the points. So you can get outwardly curved fins but not inward.
The program has fillets. I'm working on better fillets. So the function for the current fillet is called BadFillet. Should probably be NotBadFillet.
Enjoy and give me your feedback. The json file contains the presets for a few fin cans. change name fins.txt to fins.json both files must be in the same folder location. This shows what you can do with different fin tip heights.
Update 16:15 Jan 17 Aus Time.
FinFilletShape now working and all volumes join which is useful if you want to print..... :)
Update 18:50 Jan 19 Aus Time
Minimum edge thickness added. Set to multiple of printer wall print size(nozzle size normally but not necessarily) This gives you a definite edge that can actually be printed. Otherwise size of fin printed depends on slicer and nozzle size. Here you're taking that into account before you slice.
json file with presets updated with preset for single fin no fillet. You asked for it. Will show shadow of fin can but this will resolve to a single fin when rendered.

I see a lot of fin can scad files but has anyone done one for just a fin and the ability to do things like diamond airfoils and change the leading and trailing edge thicknesses? I feel like that would get more use than a fin can where you have to deal with a lip between the can and the body tube.

Already part of latest version of fin can module. Set tube thickness to 0 and fin Qty to 1.
If you don’t want a fillet set fillet radius to 0.1. It can also create a half fin of you want to create a shell In halves.
I’ll upload latest version.
Also has minimum Leading and Trailing edge thickness setting. Set this as a multiple of your nozzle diameter.

New version uploaded. There's a diamond profile single fin with min LE and TE thickness Single Fin preset. Enjoy....

I'm waiting until I can test this to make a thingiverse listing, but if anyone needs one I made a pull-pin switch mount. You'll need a 2mm bicycle spoke, SS-5GL switch (digikey), and 2-56 screws. Edit: Updated with improved tolerances and a second version for use with the metal sail switch removed.
