Enlarged Rostock Carriage from Jcrocholl modified to:

  • Include a belt tensionning device
  • Take 12x1000mm smooth rods and KB-12-WW Linear Bearings
  • Should clip the bearings (tested)
  • 0.10° bearing holder angles to compensate play
  • Changed groove to improve fabricability
  • T2.5 self locking belt mount based on belt_coupler_v6 from Okatake

Some slight updates for better printing of the belt coupler


2 out of 3 built at the Artilect FabLab Toulouse on a Prusa with 0.25mm layer height It is necessary to be at least at 0.25mm or lower to get the T2.5 belt grooves correctely

Thoses were built with 0.1 fill density but it seems a bit to light I would recomend 0.2

The 0.1° angles on the bearings is working well: no play and the carriage is going freely

The belt tensioner works, it is not prefect yet & for some reason the small bit dose not comes out quite as neat as the biger part

Thanks to the model
But if I wanted to go for smooth bars of the original design from 762x8mm?
What would I change in the code dell'OpenScad?


Just at the beginning of the carriage-V1.2.scad file you have the different variables you can adjust

H = carriage_height;
W = 60;
d = 22;
th = 4;

you will need to adjust H (the height) & d (the diameter) of your linear bearing


Are the original CAD files for this available?

The original cad file is in the download it is carriageV1.2.scad that you open with Openscad
