The set includes all the parts you need to get this awesome printer up and running. The design has been simplified to the original Prusa, so the frame is quick and simple to put together. Said to be the quickest Raprap to put together since very minimal alignment is necessary, and easy enough to assemble from a picture alone. We use modified X-Ends for easy height adjustment and Linear Bearings, also using herringbone extruder as it simply looks and works brilliantly. Traditional Prusa bed assembly is used to support Linear bearings.

• Clear Acrylic frame (wrapped in paper covering to prevent scratches in transit).
