Many times we would like the kits for electronica projects to be more and more specific.
Looking among discarded printers, in their mechanisms you can find very good wheels, rubber and plastic that still do not know q material. But ideal for certain uses.
I want to show you how I made these spare parts for printers as wheels for my electronics projects, in less than 60 minutes. This particular wheel can be found in a large number of old printers and photocopiers, usually come attached to a bar of 4 or 5 wheels per bar.
Step 1: Step 1: Materials
Common reduction motor.
Tool, calibrator or "Bernier".
Printer wheel, found at an e-waste collection site.
123D for 3D Design by Autodesk
Prusa i3 3D Printer
Step 2: Step 2: Measure. 15 Minutes.
Measure the chosen pieces.
- Measure the inside of the holes.
- Measure the exterior of the holes.
- Measure Width.
- Measure the axis.
- Measure the sectioned height of the shaft.
Step 3: Step 3: Designing. 25 Minutes
- Using the 123D design program.
If you have taken the measurements in millimeters. Then change the Units of 123D in millimeters.
- Save file with extension * .STL
Step 4: Step 4: Print. 10 Minutes.
- Using the CURA program for 3D printing.
- Open the file with STL extension.
- Because it is a very small piece you must increase the density of the final object to 75%, this already depends on how you are doing to your print3D very small objects.
Step 5: Step 5: Assemble. 9 Minutes.
- The printed part will
fit very tightly to the wheel, you will need a hammer to push it to the bottom, this also discards the use of glue.
- As you can see, it is a very good tire with rubber tires with good adhesion to any flat surface.
