**Model**

This is a lens mounting plate for the Insta360 Ace Pro. It's designed to couple with the existing bayonet mount under the official lens. This makes it much easier to design and print lens mounts for any odd lens you might want to stick in front of an Ace Pro. All you need is some holes in your lens mount to match the 52mm spaced holes in this mounting plate.

Specifically, this includes:

 - Tabs for coupling with the official bayonet mount (not identical, but close enough to work)
 - 52mm spaced M3 countersunk bolt holes
 - Sufficient clearance for an o-ring to be added to your own attached lens mount
 - Printable without supports, all angles are 45 degrees or steeper

**Hardware**

 - 4x M3 Countersunk Bolts, at least M3x12mm but length depends upon your lens mount

WARNING: These _must_ be countersunk, particularly if you have a front screen protector. There is very little clearance between these bolt holes and the screen. This was necessary for making the design printable on FDM. The twisting force of locking into the bayonet mount will not just scratch the screen, it will straight up crack it.

Ensure the bolt heads are at least flush with the bottom edge of the mounting plate. Some additional post-processing or over-tightening of the bolts might be necessary for them to be flush.

**Printing Considerations**

This is a difficult print for FDM printers. Important details in the tabs for the bayonet mount are as small as 0.3-0.8mm. The tabs themselves are only 1mm thick and need to support the weight of the attached lens mount and lens.

Recommendations:

 - Printing angle: Either tabs and countersunk head portion of bolt holes DOWN on the build plate, or print the whole thing at a very slight angle to reduce the chance of layer delamination at the mounting tabs
 - Layer height: 0.12mm or smaller
 - Speed: Slow
 - Material: PLA Plus or stronger
 - Post-processing for additional strength (e.g. annealing, gluing, plating)

**Warning**

The mounting tabs here really aren't very strong, but that is the design. They work much better in the official metal mount than in printed plastic, and they are only designed to hold the tiny and light official lens. Think carefully about whether you want to trust your lens to these tiny tabs or not. In my case, my lenses are cheap and light so it's sufficient.

I'd welcome a wrap-around mount or frame that bolts onto this if anyone has the time and motivation. That would allow good alignment, more strength and support for much heavier lenses. At the moment I don't have a design for this to share myself.

**Lens Mounts**

This print assumes you will design (or download) another model for the specific lens you want to attach to the Insta360 Ace Pro. As above, this design will need to have holes (or threads) for M3 bolts and likely a space for a nut or threaded insert.

Currently I don't have any lens mounts to share myself.

Insta360 Ace Pro Lens Mounting Plate

Insta360 Ace Pro Bayonet Screw Mount.step

This is a mount that allows for coupling between a 1/4" bolt (e.g. on a tripod) and the mount included with the Insta360 Ace Pro and other similar models.

**Important Dimensions**

Base hole: 1/4" (with normal clearance for 1/4" bolt)
Top mount hole: M5 (undersized at 4mm, intended to be threaded with an M5 tap)
Inner space for nut / tripod mounting plate: <~38mm diameter
Base plate (with 1/4" hole): 5.5mm thick

**Recommended hardware**

 - M5 Bolt x 0.8mm pitch, >=20mm long  (NOTE: The bolt included with the official mount is also M5 x 0.8mm and around the right length. See photos.)
 - M5 Nut
 - 1/4" Bolt for mounting (attached to tripod etc.), with at least 7mm of exposed thread
 - 1/4" Nut OR 1/4" Threaded Mounting plate (from the tripod etc.).
 - NOTE: 1/4" Mounting plate or nut should have a diameter of less than 38mm. Only tested with ~30mm plate, which worked well

**Optional hardware**

 - M6 or 1/4" washer, for the base of the 1/4" bolt to couple with this mount a bit more nicely, if you have enough spare 1/4" thread

**Printing considerations**

 - No support should be required, essentially all angles <45 degrees
 - Print with the base plate (with 1/4" hole) on the build plate / printing surface, or with the whole model at a slight angle for even better strength characteristics
 - Recommend PLA+ or stronger, the official mount design must be attached with fins that are around 3mm thick, which isn't much. A printed version naturally won't be as strong as the hard plastic mount that the camera comes with.
 - Recommend fairly dense infill. I used 70%. While I tried to keep walls thick, I also didn't want this being too large. A little additional infill goes a long way in making this stronger.
 - I wouldn't recommend this for "action" use. Don't go attaching it to a car or anything, or you'll end up with a cracked piece of plastic and a broken camera. Walls are around 4-5.5mm thick, and the fins are 3mm thick. If you want to risk it, try a stronger plastic like nylon.

As in the pictures, I have a couple of these very cheap tripods which only support typical 1/4" bolts that you often find on cameras, lights etc.. The Insta360 Ace Pro does not include a mounting option for these, for whatever reason. This design allows me to make use of those cheap tripods without purchasing any of the very expensive add-ons from Insta360, and without otherwise impacting upon my ability to use lens covers, cases etc.

I tried to leave enough clearance between the base plate and the arched area for you to insert whatever mounting disc / plate is on your tripod at an angle then rotate it to fit on top of the 1/4" bolt. Up to about a 38mm diameter disc / plate should be fine.

I don't intend to update this model any further, but feel free to remix this if it doesn't quite meet your requirements or expectations.
