Printruder II - Rear Breech Loading

This is a derivative of the super awesome Printruder II by Zaggo

thingiverse.com/thing:1980

1. Incorporates a prototype design by Zaggo which allows direct access to pinch wheel - Easy flossing and access to the grub screws.
2. Idler bolt is loaded at the M4 end, and then pushed towards the pinch wheel - this allows the following deltas:
- No need to dismount the motor if you want to extract the idler block
- Additional space gained allows now a 'guide' ramp for the post-pinch-wheel filament to be guided towards the heater element
- Idler block is now more secure, as it is nowhere near the insertion channel when under load

Instructions

Please see Zaggo's instructions for installation.

Note:
1. This was designed also to accommodate/fit the 688 ball bearing used as the idler as the recommended ball bearing does not fit the pinch wheel I got from MBI. My 688 Idler block is here:

2. You are welcome to modify anything, especially the filament guide ramp should you use a different sized idler bearing.

Changelog:
1. V6 - 20 May 2010
- amended part to better fit the 626 ball bearing for pinch wheel pulleys
