A Note About Our Target Audience:
This kit is for those that enjoy DIY projects. It
will require a good bit of tinkering to get the
results you want. If you have questions, which
you likely will, make it an opportunity to
become a member of our forum
(http://community.scanse.io/c/3d-scanner). We
hope you have fun building it and learning how
3D scanners work.

These assembly instructions will cover the mechanical assembly, programming and basic use of the
Sweep 3D scanner add-on.
-Soldering Iron and Solder
-Wire Stripper
-Small Philips Head Screw Driver
-2.5mm Hex Key with Ball End
The three main enclosure parts and the cable clip are intended to be printable using a consumer
desktop FDM (fused deposition modeling) style printer. You should get functional results when printing
using a 0.2mm layer height. We have oriented the available STL files in the direction we have found they
print best with the least amount of support material. We found that 20-30% infill works well. Our test
parts were made using standard ABS filament, but PLA or other materials can work too (with PLA you
need to worry about the parts melting in a hot car). You can also have these parts printed by a service
like Sculpteo or Shapeways, but it will cost much more.
Difficult to make parts: The last 3D printed part –the custom Light Pipe, is intended to be printed using
a clear resin with an SLA style printer. We realize this may not be as commonly accessible to most
people, which is why we are offering a kit of parts for sale that includes all the 3D printed parts.
We have assembled all the parts you need to make this project in one convenient kit. It includes about
60 parts, including the five necessary 3D printed parts. The 3D printed parts are made of black ABS, and
are printed at 0.2mm layer heights. The one clear component is printed using SLA technology. The only
thing not included in the kit is a Sweep sensor.
The kit is available for purchase on our website: http://scanse.io/3d-scanning-kit/

Our 3D scanner kit includes everything you need to build this 3D scanner, except for tools listed above
When working with 3D prints, it is common for slight inaccuracies to be present. Use a small tool such as
a screw driver to remove all support material and small defects.
4
Parts Needed:
-(3) 8MM OD, 3MM ID, 3MM Wide Bearings
-(3) M3 X 8MM Socket Head Cap Screws
-P0087 –Spherical Scanner Cover, Square 3D printed par t
Make sure screw holes are clear of support material. Push bearings into the slots as shown and install
the screws one at a time using the 2.5mm Hex Key as shown.
5
Parts Needed:
-OdiySurveil (TM) Simulated Roller Lever SPDT AC Miniature Micro Switch
-Female to female jumper wire cable
-10K inline resistor
-Heat shrink tubing or electrical tape
-Phillips Drive, #2-28 Thread Size, 3/8" Length
-P0087 –Spherical Scanner Cover, Square 3D printed part.
-(2) Phillips Drive, #2-28 Thread Size, 3/8" Length
Solder one end of the 10K resistor onto the common pin of micro switch. Cut the jumper wire in half, so
that each piece is approximately 100 mm (4 in) long. Strip the ends and solder one piece to the free end
of the resistor. Solder the other piece to the NC (normally closed) tab of the micro switch. Cover the
resistor with heat shrink tubing or electrical tape.
Install the micro switch into Spherical Scanner Cover in the orientation shown using the two screws.
Make sure the switch operation is not hindered by 3D printed plastic.
6
Parts Needed:
- 0.9deg Round Nema 14 Stepper Motor
- (2) M3x5mm Phillips Flat Countersunk Head Machine Screws
- P0087 –Spherical Scanner Cover, Square 3D printed part.
Cut motor wires to approximately 100mm (4 inches). Strip approximately 6mm (1/4 inch) off the ends.
Screw motor into Scanner Cover in the orientation shown.
7
Parts Needed:
-Raspberry Pi 3 Model B
-Adafruit DC & Stepper Motor HAT for Raspberry Pi - Mini Kit
-2.54mm Pitch Single Row Male 90 Degree Right Angle Pin Header
-Female to female jumper wire
Insert the motor screw terminals into motor HAT in the direction shown, then solder in place.
Next solder the large pin receptacle into the intended location.
Next, to maintain the correct spacing, slide the Female Jumper Wires onto the Pin Headers as shown,
before soldering the headers in place. Once the headers are soldered in place, remove the jumper wire.
Finally, install the motor HAT onto the Raspberry Pi 3 Model B
8
Parts Needed:
-StarTech.com 0.5m 20" Micro USB Male to Micro USB Female Cable (USBUBEXT50CM)
-Double sided tape (included on cable)
-P0090 –Spherical Scanner Cable Clip (3D printed part)
-3.5mm (1/8 inch) Heat shrink tubing
-Motor HAT/Raspberry Pi Assembly
Cut the cable about 100mm (4 inch) from the female end. Strip off the outer rubber shield of the cable
using a wire stripper blade. Separate the red (power) and black (ground) wires from the rest, and cut the
other color wires back around 20mm (3/4 inch). Strip approximately 6mm (1/4 inch) of shielding off the
ends of the black and red wires.
Remove the backing on the exposed side of the double-sided tape attached to the connector and slide
the clip and cable into the Raspberry pi. Stick the connector to the top of the Ethernet port as shown.
Slide a 25mm (1inch) piece of 3.5mm (1/8 inch) diameter heat shrink tubing over the end of the cut
wire, leaving the red and black wires poking out. Shrink in place, so that the exposed cable shielding is
covered.

Insert the cable’s red lead into the motor HAT screw terminal which read’s “+ power”, and the cable’s
black lead into the motor HAT screw terminal which reads “– power”. Tighten the screw terminals as
shown.
Parts Needed:
-14mm Circular Bubble Spirit Level
-P0087 –Spherical Scanner Cover, Square 3D printed part.
-Super Glue
10
Start by finding a flat level surface (you can use the spirit level to check for this). Insert the spirit level
into the scanner cover as shown. Then put the scanner cover on the flat level surface. Next use your
fingers or a small tool like a screw driver to adjust the position of the spirit level in the hole until the
bubble sits in the center when the scanner cover is sitting flat on the level table.
Put a few beads of glue around the spirit level and let it dry in a level position.
