3d printed sled that installs like a motor?

Does anyone make a 3d printed (or other material) sled that installs like a motor? I want to use a 54mm motor tube in centering rings inside the nose cone and use an Aeropack type retainer to be able to quickly and easily install and remove the sled.

Like this? For a tracker? This is a 38mm tube in a 54mm coupler. I made this one but lab rat makes one good stuff. Good dude too.

Pretty much exactly like that. Labrat didn't have anything with the 'thrust ring' on it or in 54mm. He was the first guy I checked. Also looked at Additive Aerospace. I use Labrat's setup in a 38mm nosecone mount but I find working with the little screws overkill for this as I am not planning to attach any recovery device to this. Also would like a 3d printed retainer similar to an Estes retainer in 54mm. ideally it would have an Eggfinder mini at the top and an RRC2+ on bottom with batteries on the back and a place for a single charge well.

Yup, those are what I'm looking for. Does anybody sell either of them or perhaps a combination of the two?

Mike at Mac performance rocketry has some NC bays..

Maybe contact Steve at SMT designs.

I think he does custom work. He may have something you need. LabRat does custom stuff too methinks.
If you're in a pinch you can use plumbing parts. I've used a sink drain pipe in nose cones before. Not elegant or glamorous but cheap. One size fits perfectly in a 38mm CR.
I'll scrounge around for my pictures.

I can print you some if needed.. they weigh about 2-2.3 Oz. for the set depending on material, so a little heavier than Aluminum retainers. They've held up really well though, with that rocket above having 4 high power launches with that set and no adverse effects. I had another kit with a the same set have the cap get a little charred due to it being a fat/heavy rocket and the deflector being flat. (and me not putting it up high enough on the rail). Just replaced the cap and it was fine. Should be about 10 bucks plus shipping. Just PM me.

Thanks. I might just take you up on that offer.

54mm retainers do stick out a bit more as well. This is a 3.05" OD FG kit with a 54mm retainer. and just the knurls stick out past the BT. OD of the outer cap is ~3.16"

I working on a build atm (Madcow Pike) that uses a MAC Performance NC bay. My setup will use a Wildman 2.2" FG bulkplate. My SMT End Mount sled will mount on the FG plate and the plate will be sandwiched between the MAC PVC screw cap and PVC cup, like a motor thrust ring in a retainer.

This is going to be in the nosecone of a Madcow/Rocketry Warehouse 4” Nike Smoke. My plan is to use a 4” coupler to 54mm motor mount centering ring and a length of 54mm motor tube. The retainer is to hold the Av-bay in place.

Yeah, no real worries about heat. I can print them lighter. Just less infill.

I really like this concept. Easy to remove.

Agreed and you can even design the threads right into the nose cone.

3D PRINTING MAKES MODULAR PAYLOAD FOR MODEL ROCKET

I recently made this to fit into a 38mm MMT that is from the MAC performance nosecone kit dr wogz linked to. This is for a TeleGPS tracker and uses a FingerTech mini screw switch to turn on. You or anyone are more than welcome to the CAD files.

This is the side that the screw switch mounts to.
