3D Printed File for 75mm Electronics Bay with a Quasar and RRC3

[conneryc]

This is what I ended up with for now using some inspiration from some of the inputs from this thread to update my initial design. As long as I only combine bodies in Fusion360 to output the STL, I can go back and change settings to match any battery/electronic board I use.

I like the built in stand-offs and battery boxes although I cannot picture how the sled will be printed without supports.

Why I broke mine into separate pieces that are bolted together, and used nylon standoffs, etc.

Yes, it will have to be printed with supports, but with my Ender 5+ I don't have any issues with that.

I've tested my latest version of my avionics sled. It worked. So, I posted it on printables.
It's made for 38mm diameter and larger rockets. Doesn't need any supports to print. Couple pics for a preview. Rest of the information is linked on printables. I also include an adapter to fit all of my bulkheads that are designed for 3+ inch diameter rockets. Maybe someone can get an inspiration from my design.

So I did some additional design work based off of additional suggestions and split the design so that no supports would be required. I modeled the original design and it would need to be printed with the stand-off's facing down and would require a lot of support structure, and to make sure the single walled support structure remained in place, a raft would have also have been necessary....possibly. So to make it much easier to print I came up with this design. Uses 3mm hardware to hold the two halves together as well as to mount the alt's. 2mm for the battery covers.

The one I did up for a buddy who is using two RC3s and wanted to have centrally mounted Lab Rat pull pin tab ended up looking something like this.

While the Qunatum doesn't NEED a switch, I put a switch on everything. Especially since when I go for my L3 switches are mandatory.

That would depend on your TAP... some require mechanical switches with them and some do not, even though the Eggtimer WiFi altimeters have a built-in switch on the deployment power (satisfying the NFPA/NAR/TRA requriement). One of my two L3 TAP's was just fine with the built-in electronic switch, the other was old school so I had to put a screw switch on the deployment power. I would expect that this would be the same with a Kate (which also has an electronic deployment power switch) and the upcoming Blue Raven (which I'm not sure about).

And it works perfectly
