The first of the 'cheapskate' triplets. This used stainless v-wheels and a steel square stock shaft. The problems i found was it needed the detail of a 0.2 nozzle or resin (I used resin) to make the carriage parts. And, assembly was an absolute pain with no adjustment. Sadly, while it worked great, it was leaving marks on the steel which meant over time it would wear grooves.
If anyone wanted to try this with acetal inset v-wheels (See T105 for what I mean), then it may work much better if you can cram eccentric bushings into it.
