Andy - Beta MIRACO Showcases of Bones, Shells, Art, Design, Modifications

[Rilot]

Pre order MIRACO now on Revopoint official website: Revopoint MIRACO: Big and Small Object Standalone 3D Scanning

Please note that this is a beta prototype, and the product ID and packaging are for reference only. The final mass-produced version may have differences.

Revopoint are cutting the cord and giving us the ability to scan without a PC or Mac.

MIRACO is a 3D scanner that provides a range of features to make scanning and processing models quick and easy. You can check the key features on the KS page.

Video unboxing

Revopoint Miraco unboxing

Here it is. Miraco comes packaged in the usual high-quality box made of thick cardboard with a glossy finish.

Inside is the usual array of plastic sealed items.

Removing the packaged items reveals the scanner, turntable, tripod, and bust. Note: the multi-country adaptors are unlikely to be provided with the final model as a country specific PSU is likely to be provided.

A good amount of markers are provided. These are the newer, reflective markers that we first saw with Pop3. The scanning market mat is also in the box.

The bust is provided again. This is the same size as the one provided with Pop3 and Inspire, rather than the smaller one that comes with Mini.

Here is the contents of the box, all set up and ready to go.

Selfie mode!

From top to bottom: Miraco, Mini, Inspire, Pop3, Range.

And here is Miraco powered on after I’ve done an initial scan of the bust. From unboxing to starting to scan is literally 2 minutes - which is the time the initial boot takes. There is no software to install. No cables to mess about with. Just turn on, scan, and go.

To facilitate easier rotation of Miraco I designed a gimbal. This holds Miraco at its center of mass and has two handles, one to rotate it and the other to lock it in position.

The files are available here: Miraco_Gimbal.zip - Google Drive

To complete you will require:

2 x M8x45mm bolt
2 x M8 nut
1 x M8 Nyloc nut
1 x 1/4"-20 nut
1 x 1/4"-20 bolt to hold Miraco tripod mount. You can use the mount for the wrist strap.

Using Miraco for reverse engineering: Small part - 34mm

This is part of a wall mount for a small secutiry camera. Very glossy surface.

Let’s make it in CAD

Import the mesh to Fusion 360

Create a mesh selection sketch

Edit the sketch and use Fit Curves

Back in to the solid workspace, select revolve

Check it agrees with the mesh

Create another section sketch to capture the indentations

I’ve made it as a primitive here

Make a circular pattern of the new object

We want 8 indentations

Use the object as a cut tool to form the indentations

And fillet them

Make the threads - I measured these as 1" BSP threads

And here’s our finished model, ready for modification. Miraco has enabled us to replicate the object.

Let’s print it and see if it works

Perfect

Using Miraco to design a part that fits to a complex object

Problem
The controller for my drone (DJI Mini 4 Pro) only has mounts for a neck-strap at the rear.

This means it flops forward when not supported. I would like a way to hold it at it’s center of mass.

There are trays that mount to the controller but they increase it’s bulk quite considerably. Ideally I want something that mounts a strap here:

Scanning
In order to create the part, we first need to create a scan of the DJI RC2 controller. It doesn’t need to be mega-detailed but we might as well show off Miraco while we’re doing it:

Getting it in to CAD
There are several ways we can get this model in to CAD. We could re-draw it from section sketches like I’ve shown before but for this project, we’ll use a different way.

Triangles to quads
I want to create a T-spline model of the controller in Fusion360. Unfortunately, the mesh to T-spline converter can only deal with quad meshes and the output of Revoscan (and all other scanning tools really) is triangles. We can covert the model to quads using a nice, free tool called Instant Meshes: GitHub - wjakob/instant-meshes: Interactive field-aligned mesh generator

Let’s load up our scan; click Open Mesh:

Our mesh is loaded and ready for conversion:

At the moment, our target vertex count is way too high at 100k. Fusion360 will have a fit. We want that around the 10k mark ideally. Move the slider to 10k:

Next, hit Solve under Orientation Field

Our mesh will have lots of pretty colours on it now.

Then, hit Solve under Position Field

And now our mesh is all squares:

Hit Export and choose Pure quad mesh (this will ensure that all the facets are quads and that no triangles remain.

Finally, Extract Mesh

And Save

Now, over the Fusion360:
Create a new project, import your quad-mesh and orientate it so that it’s aligned with X, Y, and Z.

Next, under the surface tab, select New Form

Then hit Convert

We want Quad-mesh to T-Spline

Hit OK, and Fusion will chew on it for a while, then hit Finish Form

We now have a defined solid in Fusion that we can do all sorts of things with:

As you can see, we can cut it up just like a normal solid

OK, back together we want to make a copy of it

The new object, we want to scale it to make it bigger. I want something that will fit around the controller but follow the controllers lines. Let’s make it 1.1x bigger. Make sure to scale from the origin rather than a corner.

Now, let’s cut it up and make the rough model that we want:

Now we have our rough model, let’s put it over the 1.0 scaled original model and then use that model as a tool to cut out from our new part:

We end up with this, ready for an attachment to be added:

A quick bit of CAD and we have our part:

This is what it looks like rendered in Fusion:

Let’s print it and see how it fits:

From idea to CAD in 10 minutes with Miraco

The fantastic thing about Miraco is the ability to just pick it up and scan without having to mess with anything else. I did just that with this example.

I own a Dyson V11 which is a great little cleaner with one glaring omission; the trigger doesn’t lock, so you have to hold it down all the time.

I looked at various off-the-shelf solutions and all of them came up short. Then I was sitting on my sofa and thinking about things and the following thought came in to my head: “The Dyson has a trigger. What else has a trigger? - firearms have triggers and some of them have trigger blocks to prevent you pulling the trigger. What if a trigger block could work the other way around?”

So, I grabbed Miraco and the Dyson and started scanning. Doesn’t need to be pretty but it does need to be accurate:

It took all of 5 minutes to scan and get the data I need with Miraco

This is the area we need:

Right, in to CAD we go:

Using the slice and sketch method I’ve shown before, we end up with a model of the V11 trigger and handle:

I’m not going to go through the full design process of this part as it’s not relevant for this but, after an hour or so I came up with this:

Cutaway showing how it functions:

Let’s print it, assemble it and see if it works:

Here you can see how it attaches and why an accurate scan was so important. I couldn’t have made this without a scanner.

Once again Miraco has sped up my workflow no end, and also made scanning more convenient

Scanning a skull in Single Shot mode

Single shot mode allows you to be more selective about what data you capture and from what angles. It lets you take your time and line the frames up perfectly.
Very useful when your access to the object to be scanned is limited.

Look at the detail. This is in standard accuracy, body mode and only a handful of frames.

Incredible showcase, thank you.

Thankyou Gary. It was a lot of work.
