Lightweight adapter to mount a Piko BLX flight controller that uses 20x20 spacing to a 30.5x30.5 spacing used by Naze/CC3D/SP3/etc

Uses four M3x6 screws and nuts.

6/14/2016 Added a version with tabs instead of screw holes. Use flexible filament and pull the tabs through the board holes.

12/10/2017 Added a 30.5x30.5 to 16x16 adapter

any chance you could modify it to 30.5x30.5mm to 16x16mm?

Sure thing. Should be available now.

wow, that was quick. Thank you!

Hey can you make a 20mmx20mm-16mmx16mm?

20x20 and 16x16 don't play well together. The bolt heads or hex interfere with each other as it's too close. I've designed one but I don't like it at all.

I want something like this were i mount my 16x16 flight controller in the middle and the 20x20 will be on the hex. so the 16x16 is just floating.


I think the 20x20 is m3 then 16x16 is m2

Yeah. I don't think he ever actually tried to build that. The head of the M3 screw/nut will interfere with the M2 bolt itself. I've done it. It doesn't work. The problem isn't as easily solved as the 30.5 to 20 adapter.

:( aw man. thanks anyways.

Hi slovenian6474, This is an Awesome Design for the Piko, But i just received a test sample of a new flight controller that is coming out soon. I was wondering if you can redesign this one a little bit.? The dimensions on this controller 25mm X 25mm at the center of the holes. The Version 5 works well for my Piko so i would like to stay with version. Let me know what you think...
Thanks: Terry

I looked into it just now. 25mm spacing is getting dangerously close to 30.5. The 25mm screws or tabs would actually interfere with the 30.5mm screw heads or standoffs. The FC would also need no corners. I don't think simply moving the 20mm to 25mm would work. It'd need a different approach.

If you want to message me with more details of the FC, I could probably come up with something.

Nice design. Any suggestions where I can get this printed?

Send me a message

Thank you. Stylish too.

I love printing with TPU flex filament. Could I request you make a version where instead of using screws for the 20x20. I'd like little nubs I can simply pull through to secure the Piko FC to the adapter. Hope I explain it correctly.


Thanks. I think I know what you're talking about. That's a good idea and should be easy to implement. Would you mind testing it?

I would love to test it. Thank you.

Ok. Flexible mount is up. Let me know if it works. If it doesn't work too well, let me know what to change.

Thank you. I think it will work out good. Only thing I can see that is an issue is the new flex version standoffs are low. So not enough to allow the SAT port at the bottom to clear. I personally remove the SAT port myself... but for other ppl who keep the SAT port... you'll need to raise the height of the standoffs to the original thickness. Hope that makes sense. I can send a picture if you need it.

Whoops! Built it off the old model that was shorter. I've updated the file.

I admit, I am having a hard time to get the nubs through the hole. Could be due to the tolerance of printing the TPU. Perhaps a smaller diameter to make it easier to pull through the hole? Right now, my printer seem to print the diameter of the nub at about 3.67mm.

Alright. Try the V4 adapter and let me know how it works.

Hi Timothy and thank you.

What's the current diameter of the flexible v4 nubs? Though it's hard to get exact measurement with my digital calibers because the TPU is flexible...my printed nub is about 3.25-3.3mm. Still a tight squeeze through the Pico FC holes. I wonder if making the nubs exactly 3mm would allow a friction fit. Because the tolerance is so tight at this size?

Current diameter on v4 is modeled at 3.5mm. So it seems your printer is undersizing them ~0.25mm. I'll make v5 at 3.2mm so it should come in right around 3.00mm on your printer.

v5 is up with 3.2mm diameter. I also uploaded v6 which is 3.00mm diameter Try those out and let me know.

Hi Timothy,
v5 works well for me. Slides through with little effort. V6 was too loose for my liking. Perhaps 3.25-3.30mm maybe perfect. Anyways, I'm happy.

The bottom standoffs does rub against the SAT port by a hair. Easy to remedy so that's not a concern for me. Besides, I'm removing my SAT plugs anyways.

Thanks again.

Post a pic! I'm curious to see how it turned out.

Of course. I had planned on to.

Just uploaded a pic. Sitting inside the SCX200 at the moment.

Great. Let me go try them and report back. Thanks so much.

Sure thing. Give me a few days as I've a little busy at the moment.
