Customizable Small Linear Carriage Generator by ctheroux

Last crawled date: 3 years, 1 month ago

This set of files generate the printable parts needed to build a small linear carriage. This carriage is designed to be a Z axis carriage while http://www.thingiverse.com/thing:1411601 is the Y axis. The X axis will be uploaded soon. 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 "Front Plate.scad", "Motor Mount.scad" and "BearingHousingMount.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 given files are for:
20 x 20 mm V-SLOT™ Linear rail (337 mm in length)
1 Nema17 stepper motor (17HS8401)
4 Delrin V Wheel™ Kit with spacers
