RepRap Wilson is derivative from Josef Prusa's i3 with the following goals:
- Replace the waterjet metal frame / wooden box frame with an inexpensive and rigid frame made from standard 2020 Aluminum Extrusion.
- To make the build volume parametric (easy to scale up or down by 50%), with a parametric BOM tool (spreedsheet) to assist in part selection.
- To simplify construction of the printer by reducing vitamins and including detailed assembly steps as part of the design files. I've made an effort to reduce the number of unique parts (nuts & bolts) as much as possible. I've also incorporated single-piece Y ends that eliminate about 20 more hardware items.
