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 models. 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 actual files are for:20 x 40 mm V-SLOT™ Linear rail1 Nema17 stepper motor (17HS8401)4 Delrin V Wheel™ Kit with spacers1 8 mm lead screw (four starts) easily availabl
