This set of files generate the printable parts needed to build a linear carriage. It can be heavily customized.

The Libre Office Calc file is used to compute some key values needed to create the printable parts. Some resulting values have a variable name on the right. These values shall be copied into the Parameters.scad file. It is the only OpenScad file that contains modifiable parameters.

Once you have customized the parameters in Parameters.scad, open the files “Linear Carriage Double Track Bearing Mount.scad”, “Linear Carriage Double Track Motor Mount.scad” and “NutBracket.scad” with OpenScad, render them and export the three model. Before printing or cutting material, verify carefully the overall part sizes. Invalid parts may be generated if incoherent values are inputted.

The value given in the files are for:

  • 20 x 40 mm V-SLOT™ Linear rail
  • 1 Nema17 stepper motor (17HS8401)
  • 4 Delrin V Wheel™ Kit with spacers
  • 1 8 mm lead screw (four starts) easily available from Chinese suppliers
  • 1 flexible 8mm – 5mm coupler
  • 2 608ZZ bearings with a 8 mm washer
  • 8 T-Slot inserts with the required M5 screws
  • 4 M3 screws to mount the motor
  • 5 M5 screws and nuts to mount the V Wheels
  • 4 M3 screws and nuts to mount the nut bracket.

The Nut bracket is not shown on the picture of the parts, but the OpenScad file is provided. Nevertheless, it is on the final prototype picture.
