Minor mods to Rostock

Hi All,
Just thought I would post some minor updates that I made to my original Rostock.

Pulley Case Covers: I found that anytime I put anything down on the desk it would seem to be attracted to the moving pulleys and belts at the base of the rostock while I was in the middle of a print job hehe.  So I made up some simple covers for the motor mount at the bottom of each axis.
The stl can be found on thingiverse: http://www.thingiverse.com/thing:53556

Kossel Effector: I decided to replace the original rostock effector with the newer simpler design from the Kossel. This image shows the original design sitting on the print bed with the new, more simple one from the Kossel already fitted floating just above.
The new effector design is lighter, allows a more unobstructed view print job in progress and allows the effector rods to be attached in a more simple and secure fashion.
If you do use this part for the standard rostock you must make sure that the spacing between the effector rods at this effector end is exactly the same as it is where they on the X,Y and Z axis. The scad file from the kossel will allow you to adjust that dimension if necessary. I just used the standard spacing as the spacers from my Heim joints allows it to fit perfectly.

 

 

 

Herringbone Gears: Finally, just because I was board, I replaced the standard gears on my extruder with herringbone gears. These have less play and seem to be a bit quieter.
I just used the standard parametric herringbone gear openscad file that you can find on thingiverse adjusting the gear ratios for the ones I use on my wades on this Rostock.
