Summary

This 2D model is suitable for cutting the parts of a replacement wheel for a trolley bag (wheelie bag). The wheels of different bags are probably not standardized, thus you may need to adjust the inner and outer limits of the model.

The attached SVG model is suitable for the following dimensions:

  • outer diameter: 64mm
  • hole diameter (center): 22mm
  • hole diameter (both sides): 12.5mm
  • width of center disc: 9,5mm
  • width of both side discs: 6,5mm

Slight differences of the outer diameter or the width of the discs should pose no problem. But you should take care, that the inner diameter of the two outer discs fits to your trolley.

Instructions

Material:

  • wooden panels of 6,5mm and 9,5mm thickness (or whatever is appropriate for your trolley bag bearings)
  • wood glue

Tools:

  • a CNC mill or a laser cutter
  • clamps (or tape)

Manufacturing:

  • remove all plastic parts from the axis of your broken wheel
  • measure the diameter of the metal bearing of the axis
  • adapt the 2D model, if necessary (e.g. with Inkscape - http://inkscape.org)
  • create a toolpath/GCode (e.g. with PyCAM - http://pycam.sourceforge.net))
  • command your machine to execute the GCode (e.g. with EMC2 - http://linuxcnc.org)

Assembly:

  • push the first outer disc into position (slightly more inwards, than necessary)
  • apply wood glue to this disc
  • push the inner disc into position; add the small break-away piece as well
  • apply wood glue to the inner disc (facing outwards)
  • push the second outer disc into position
  • clamp the three discs for some hours
