DJI Osmo Nano Bold-Down FPV Mount Project

Companion project to my other parametric configurable FPV designs: 

Protect your GoPro Hero 6 through 13 camera with the best mount in FPV! Max protection with TPU in front of the lens but still with a clean image. How? I've modeled the camera's field-of-view (FOV) and built my design around it. My flexible on-demand design can fit 300 different frames, different camera angles, ND filter options, positions, etc.

2025-10-01 Update: Design can now support vertical camera mounting! On-demand only, as always
2025-09-30 Update: New design with side-strike protection

This is an ON-DEMAND design!

Only a few basic 10º versions are posted here, everything else is made for you (for free) on my 3D Design discord. You choose what options, I make you designs, you send me photos of your builds! See the Steps below.

Step 1: Pick your quad(s)

What quad you got?? I've made a highly flexible, adaptive system, with over 320 different bases, new ones every day. See the files on my Action2 design for some common ones!

Step 2: Pick your uptilt angle(s)

• Cinewhoops: 10-20º
• Cinematic/Long Range: 20º
• Freestyle: 25-35º
• Racing: 40º+

Step 3: Pick your ND Filter (or none!)

1. Badass all-around TBS-style plate-glass
   1. 2.5mm thick filters [tbs site] Also compatible with the similar 2.5mm thick Camera Butter insert filters.
   2. Held in from top and bottom notches, inserted from either side. 
   3. Also works great without filters (and even provides extra protection over no-ND option). The most flexible option!
2. Lens-replacement style
   1. These don't need anything special, just replace the lens with a darker one!
3. Over-Lens NDs
   1. Works.. just gigantic, less protective, and usually expensive. 
   2. Leaves a huge gap when filming without the ND

All ND versions/tilts are configured on-demand! See Step 8!

Step 4: Camera Positioning

1. Standard
   • Props probably in view
   • Full size underbelt slot (see below. adds extra protection option and reduces vibration / image jello)
   • Your quad's frame takes head-on impacts, camera hits second.
2. Forward
   • Props hidden (depending on frame)
   • Small underbelt slot (if any)
   • Camera is more exposed. Less great for bando bashing.. but also this mount offers lots of protection.
3. Several other non-standard options are possible. Do ask.

Step 5: Bolts & Base Options

• Base Thickness:
  • Standard is now 3.4mm thick. 
  • Thick is 4mm
• Bolt style:
  • Standard size for M3 bolts is a 6mm diameter bolt-head.
    • Perfect for nearly all M3 bolts and plenty strong.
  • Big-Boltz, for M3 bolts, has a 8mm diameter bolt head.
    • Great for things like these FPV Countersunk Washers if you want extra strength/flair.
  • Shoulder-bolts option. 
    • Great for products like the QuadMula PS-3 Spacers that come with the Quadmula frames.

Step 6: Extra configuration options

1. X-Offset: Make the lens more centered over the FPV camera. Many pilots prefer this.. I support it!
2. Cut-Away Minimal version
   1. Useful for long range quads or cinematic rigs.
   2. See the second photo in the main image area (or here)
3. Underbelt slot allows for an optional battery strap around the camera for extra ejection protection and slightly more front-end hit protection.
   1. Also seems to really reduce jello by allowing for a smaller area for vibration transmission to pass through. Great!
   2. Not included by default on standard mounts.
4. Base thickness 
   1. It's now 4mm by default and holds up great!
   2. Beware: My oldest designs may have been as thin as 2.2mm. 
5. Different camera wall size

Step 7: Request the STL!

Send me a message on discord! Haven't found a better way to get y'all your STLs yet! Everything is generated on-demand with the settings you ask for. Why?

1. The STLs in the ‘files’ section are outdated. 
   • I can't possibly keep re-exporting, uploading, and organizing 80+ STLs after each tweak!
2. They don't have the configuration you want. 
   • ND filters? Angle that's not 25º? Underbelt option? Thicker base?
   •  I can't possibly upload all the variations!

So request it! I've set up my discord as a cool queue system. I'll get you your custom STL in less than 24h, usually right away.

Step 8: Print the Mount

• Print with TPU filament, slowly
• Use tree support if your slicer supports it
• Best printed on its side (as oriented in the STL).
• Use 2 perimeter walls for most setups. 3 walls for bando bashing.
• Infill: Use 20 - 30% cubic infill
  • 15 - 20% for most setups
  • 25 - 30%  infill for bando bashing
  • Really don't go above 30% infill, it just adds extra weight but no strength benefit.

Also look at the makes section for other users' tips!

Step 9: Print the Back LCD Wedge (new rev 6+!)

New Modular Battery Protection Wedge! Keep your battery in-tact, even after huge direct-hit crashes. My new modular wedge design slots into the back of the mount and fills the gap between the camera and your battery.

Pardon the photos showing my Action2 Mount design. Still need some new photos of this cam!

The new design prints in two parts. Easy access to the rear bolts! Easy weight savings for long range flights! 

Wedge-specific print settings:

• Also print in TPU
• Just 1 perimeter wall! More is wasteful and overkill for this part.
• Use Cubic infill pattern
• Between 16 - 26% infill depending on how fast you're flying.
• Optionally: zero top/bottom layers.. saves weight and looks pretty cool.

Also look at the makes section for other users' tips!

Step 10: Post your makes!

Please post 'em! Really! Take a cameraphone photo with your dope color matched mount in all its glory and show it off! Plus it really helps get this design out there to the world

That's it! Go fly!

Again: BEWARE, what's uploaded here is OUTDATED FAST

Seriously. I just can't keep re-uploading and categorizing 120+ STLs. Tweaks are always happening based on feedback. Thicker base, more material here, less there, on and on. So:

Want the Latest Version? Missing your Quad? ND Filters?

Message me! discord! The 120+ mount designs I've uploaded here (see files!) are updated after every tidbit of feedback I get and are all already out-of-date. Message me for the latest version!

New quads/variations for folks all the time. I may already have the one you need.

It's really zero trouble, I can export configurations on my phone and send them over instantly.

What sort of frames are supported?

• Classic designs from the Apex by ImpulseRC, to the Quadmula Siren, and to the Y6 by Freelon and everything in-between
• Open source designs like the OpenRacer for racing and the TBS Source-One v1, v2, and v3 for freestyle

Please Post Your Makes!

Please post 'em! Really! Take a cameraphone photo with your dope color matched mount in all its glory and show it off! Plus it really helps get this design out there to the world.

Sharing & License & Stuff

The LAST thing I want to do is restrict anyone from sharing. But. PLEASE share links to this printables page, not the STLs. Here's why:

1. This is under active development. The STLs WILL CHANGE and get better.
2. The documentation is really important here, and I'm sure there's stuff I'll be adding as feedback comes in.
3. The community is important, I want people to reach out and join the discord not download some STLs and go it alone.
4. It's just a super dick move to repost designer's stuff. I've spent a long time making, testing, and documenting this and my only reward is that little stupid ‘like’ counter, download counter, and photos/stories from users. DON'T DEPRIVE ME OF MY ONE SENSE OF SELF WORTH

The actual license is Creative Commons (4.0 International License) Attribution—Noncommercial—No Derivatives. If you'd like to print this commercially then reach out to me with a direct-message on discord and we can talk. Flying professionally using my designs is fine– though please do consider donating to support my work!

Remixing

Please chat with me in my discord server before making or posting any remixes. 99% of remixes have been manual recreations of things I don't want posted and that take me 20s to make for you directly. Save yourself the trouble and me the heartache.
