Vik Olliver (vik (a) diamondage dotty co dotty nz) is one of the core RepRap team (aka reprap-admin) and works out of a zombie-proof industrial unit in Henderson, New Zealand.

He has a wife, two kids, seven cats and more repraps than you can shake a length of 8mm rod at.

Under the guise of Diamond Age Solutions Ltd. he pushes PLA filament and 3D printers to the addicts...

Biographical Data

MkII Extruder made from Adrian's FDM'd parts. The clamping effect is achieved by rubber rollers salvaged from an old printer paper feed roller, and the holed for the studding were drilled out for M4 'cos M3 studding was hard to get.

Some of the washers are very close, and in unimportant cases actually overlap. This can - and will- be solved with a few deft strokes of the file. The screws are not cap screws as they're scavenged from parts kindly donated by ECONZ Wireless.

The gearbox is also ECONZ salvage, and I've replaced its original 6V motor with a 12V motor from an Epson tally printer. The screw thread is not yet fitted, and so I've not built the mounting for the gearbox - it's just held there by the clamp.

First 3D Cartesian axis

No electrics other than the motor on the stage though. Should take standard circuitry, which I may try building on vero. But it does have steppers on all 3 axes:
