3D Printing NEW Modular 4” Sled design

[cwbullet]

I am designing a new sled design. I plan to have inserts to be able to swap out altimeters. The two inserts shown are for the RRC2+ and RRC3.

What cad software do you use?

Tinkercad and Fusion 360

I have made it thicker to route wiring and added a place on the edge for a Fingertech switch on both sides.

Tinkercad and Fusion 360

Why tinkercad if you know fusion? I thought it was intended to be super easy to learn but not powerful?

I can easily do Tinkercad in the car on my iPad and at work when I have down time. Shhh!

Ok I won’t tell, if you don’t tell my English teacher

I am designing a modular AV bay with inserts to swap altimeters.

So far, it used fingertech switches. I have an insert for RRC2+, RRC3, PF SL100, and SL CF.

Any other altimeters that you suggest?

Eggtimer Quaser, Quantum, Quark would be what I'd be looking for. I need to put together a 4" ebay and have a Quasar and Quark with fingertech switches on hand.

Telemetrum.

At 4" and above, you can easily fit everything on a flat plate. It's the smaller diameters that really benefit from the geometry manipulation of 3D printing.

I will

I have several but have yet to fly one. How large are the screw holes?

I haven't flown a Quasar yet either. Got two built and ready to be installed and another two on the way. I'll measure the holes later and get back to you.

I haven't turned my printer on in about a year, but I'll give this a try if you share the files after you finish up.

Altus Mini, since it's become the replacement for so many folks who used to rely on the SLCF

I am working on this for BT50 and above using the Telemetrum EasyMini. BT60 completed, but not flown. Altimeter, battery and screw switch on a relocatable platform.

How about some photos of what you're doing?

 

[cwbullet]

I will post some images tonight.

The side of the design shows the slot for the FingerTech switch. The groove is for the wires.

Bottom od the sled.

Next week, I will be printing the main sled and fitting my parts to it.

I am just struggling with finding a drawing with deminsions and screw sizes for the Eggtimer altimeter. Does this exist?

Does this help?

And Proton...

I've standardized on Lab Rat Rocketry pull-pin switches. Adding a sled that uses those would be the bomb.

I can do a model for that also if there is enough interest.

I missed that - yes. What size screw does it take? Not clear from the pdfs.

I believe all the Eggtimers are 4-40. I know the Quantum is.
