Description Files (32)

Summary

An alternative X-carriage for Geeetech Prusa i3 X. Made for a smooth rod separation of 45mm (not the default 70mm). It was designed to have some minor advantages as compared to the stock Geeetech carriage set:

Easier removal of the extruder from the carriage: Unscrew two M4 screws from the bottom and pull the extruder forward through the gap (backplate.stl)
Cable gaps for hot-end cables and motor cables at the bottom of the back plate -> No loss of build volume in any direction
Back-mounted (M3 screw and nut) cable holders and pass-through-holes allowing to fixate cables at the back side (back-cable-holder.STL) - alternatively a cable tie can be used by means of a provided additional hole
Fan shroud for the existing 40mm fan to cool the hot-end a bit (fan-duct-1.stl)
3 sets of frontal mounting holes made for M3 nuts (Separation: 24mm, 40mm and 78mm) - easy and convenient mounting
Circular fan duct for perfectly uniform cooling flow (fan_duct.stl) - The duct is designed to have a distance of 3mm from the print bed to not to rip off the 4 binder clips. However, the minimal distance from the heater block is 1mm. Two LED mounts are provided.
Less weight than solid acrylic
The heads of the screws and washers are hidden within the backplate

Limitations:

The provided belt fixation (belt_fixation.stl) can only be used with low profile SC8UU bushings/bearings (i.e. http://www.thingiverse.com/thing:1196801)
You'll potentially need shorter M4 and M3 screws. This was designed for 10mm M3 screws and 10mm and 16mm M4 screws.
The back cable holder may limit your maximum/minimum X distance (in my case reduced by -3mm)
There is not much room for the circular fan duct. Take care not to melt it by the heater block.

_Update 23.01.2016: Fixed Belt fixation: Belt was not fixed properly
_Update 28.02.2016: Added version for GT2 timing belt with 1.38mm height (Attention: some GT2 belts have a height of 1.7mm or 1.54mm)
_Update 18.10.2016: Widened support for backplate (backplate v1.1.STL) for larger nozzle diameters.
