The XTION normally stands on a base for table-top use which is not aimed to be hand-held. This 3D printable file was designed to fit the ASUS XTION making 3D scanning much easier and the device more comfortable to use.
This article also covers the basic steps on how to 3D scan a human body and finalise the mesh in Autodesk MeshMixer.
Step 1: Download the Free 3D Files
Step 2: 3D Print the Grip and Lens Cover
When the 3D print is done, remove the parts carefully from the build platform. In most cases wedging a sharp strait painters spatula between the bottom of the 3D printed part and the build surface, releases the objets nicely.
Step 3: Attach the Grip to the ASUS XTION
- Do not over-tighten the screw!
- The furrow points backward away from the lenses
- Insert the USB cord into the furrow
Step 4: Insert the USB Cable and Ferrite Core
Step 5: Secure the Bottom Part of the USB Cable to the Handle Base
Step 6: Bottom Part Attaches to Flat Surfaces
Download the DXF-file as a drill template. Print it on paper and glue it to the surface you want to drill holes into.
Step 7: Place It Upright on a Table
Step 8: Protect the Optics!
If this this still happens or for instance the covers flexible legs break for some reason, just 3D print a new one! :)
Step 9: Stows Away Nicely
Step 10: How to 3D Scan a Human Body
Start a 3D scanning software on your computer. Below are a few compatible with the XTION, Kinect and other PrimeSense-enabled hardware devices.
Step 11: Start the 3D Scan and Export to STL
Once you have finished the 3D scan, export the file as STL format. This will then be able be imported into a 3D print mesh healing software such as Autodesk MeshMixer. 3D scanning softwares usually have mesh fixing features which can be valuable to make a water-tight mesh, but i most cases further adaptation of the result is necessary and therefore a software with more advanced features is preferred.
Step 12: Prepare the 3D Scanned Mesh for 3D Printing
- Import your 3D scanned mesh
- Press S to start selection mode
- Click once on the main mesh to select a small part
- Press E to expand this selection to all connected triangles
- Press I to invert the selection
- Now all eventual small islands are selected
- Press X to delete them
- Save your MeshMixer project file!
Step 13: Turn the Model Upright
- Press T to start transforming your object
- Grab the rotate gizmo and orient your model as you desire
- Press Accept to finalise the transformation
Note that you can also move your model to a centered position in this same step by grabbing the arrows of the gizmo.
Step 14: Rough-cut Away the Bottom Part of the Mesh
- Choose Edit > Plane Cut
- Use the rotation and placement gizmos for the cut plane
- Note that the transparent part of the model is deleted in this step
- Press the small blue arrow to reverse the direction of the cut
- Press Accept to cut-away the lower part of the mesh
Step 15: Inspect the Model for Holes and Defects
- Choose Analysis > Inspector
- Lots of needle-shaped pointers appear
- Press the ones that you find fix most issues
- Do not press the needle indicating the lower big cut hole. Leave that for later.
- If a cut does not work the needle turns black. Just ignore those and keep fixing others.
- When most or all (except the cut hole) are finished, press Done.
- Repeat this step several times if necessary.
(Probably you will be thinking of voodoo dolls now! :)
Step 16: Manual Mending of Holes
Rotate the view and look at your model to find obvious parts to fix manually. In most cases it is easy to select the bad part and delete it to create a hole. This removes the unwanted surfaces and the hole can be filled instead. There is a tool in MeshMixer that does this in one step.
- Press S to select and paint a part of the mesh (for instance surface spike or the area surrounding a hole)
- Press F
- See the MeshMixer magic happen!

Step 17: Make the Final Cut for the Bottom Part of the Model
- Choose Edit > Plane Cut
- Place the plane where you want to cut
- Make sure to select Hard Edge
- Press Accept to create a cut and also make a solid flat plate on the bottom of the part.
The original raw 3D scanned mesh, as well as the MeshMixer project file and the final STL for 3D print can all be downloaded below.
Step 18: Analyse the 3D Model for 3D Print Overhangs
3D print software usually takes care of this nicely but it is always great to have perfect manual control of where the support structures are placed. MeshMixer has powerful features to help you do this such as follows:
- Choose Analysis > Overhangs
- You can now see a red colour on the overhang parts of your model
- Press Support All Overhangs to create support structures automatically
- Hold down cmd/ctrl and left-click on the structures you want to remove
- Hold down Shift and left-click-and-drag on parts where you want to create new structures.
For a rough overview of how this model was fixed please see the video below.
Step 19: 3D Print It!
- Load the STL file into your 3D printer's software.
- 3D print it!
- Give it away as a gift to friends
- 3D print new ones! :)
