The first item I've designed myself and like all good things it's terrible simple but serves a purpose.

A simple spacer bar for the stock extruder on a mono RepRapPro Mendel.

The picture shows the first version of this which was just a cube with 2 holes in it attached to one of our Mendels, it allows the stock extruder to be positioned away from the main bar giving a few more mm's of Z height.

Will look at modifying it to incorporate the bar clamp portion as well so that it's a replacement part rather than an additional one.

Final version now uploaded which includes the spacer bar integrated into an M8 bar clamp.

You'll need an additional m3 bolt and some m3 washers and nuts to attach it.

I'm going to stop playing with this now, added final version which is not as tall as the original as it doesn't need to be,

Added a parameter arm_length to adjust how long the arm is :)
