Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3065295.
This is a set of extruder mounts for positioning the Extruder Assembles on the Zonestar P802QR2 X Axis Carriage. The advantages of this are:
1.Reduces the Boden Tube length by a third and therefore reduces stringing (see uploaded image of comparative stringing tests).
2.Makes it so much easier to change, add and remove filament.
3.Offers further options for positioning of spool holders.
4.Reduces clearance height of printer.
There are 3 types of mounts uploaded:
1.Direct Mounting - Hole fixings and aperture for fixing the Extruder Assembly directly to the modified X Axis mounts. This is the simplest mount but does position the assembly outlet tube below the outlet tube on the hot end. This will result in a slightly longer Boden Tube to allow for the bend radius.
2.Extended Plate - Straight - RH & LH extended plates are included to fasten to the mounts to elevate the Extruder Assembly outlet tube above the hot end outlet tube to provide a better bend radius for the Boden Tube.
3.Extended Plate - Angled - The same as item 2 but the extension plates are angled to improve bend radius to Extruder Assembly tube outlet. The angled mounts also allow for the spool holders to be sited to the rear of the printer.

Disclaimer:
Mounting the Extruder Assemblies to the X Axis carraige will add additional weight to the X axis. This therefore will apply greater strain to the Z axis stepper motors. So Far In the tests I have undertaken I have had no problems but with the Zonestar`s overall component quality being so poor its worth reiterating that this should be done at your own risk.
Print Settings:
0.2 Resolution, To provide a strong thing I printed with 3 perimeters & 30% infill. No support required other than the fixing bosses in the angled extension plates (this will print without support but a few custom supports will probably provide a neater fixing hole).
