There has been a fair amount of interest in a hardware kit, so I've been investigating pricing.

What would you want in a hardware kit for the extruder?

  • Screws, bearings, pulleys, belts, springs and insulating tape (of course)
  • Hobbed bolts?
  • Hot ends?
  • Motors?
  • Z probe servo?

If you have stock MakerFarm-shipped RAMPS electronics, you might also need

  • A4988 driver board
  • RRD Fan extender

to control the extra motor and print cooling fan.

Everything (except the RAMPS electronics) can be sourced from a combination of MrMetric, MakerFarm, Pololu, McMaster Carr, HobbyKing, Harbor Freight and a couple of Chinese eBay sellers for around $253, including shipping to the US (2-3 weeks). I'll upload a shopping list soon.

I've been investigating volume pricing, and I could probably offer an all-inclusive kit (everything except the RAMPS electronics) shipped Priority Mail in the US for a little less (maybe $230, depending on sourcing).

How much demand would there be for such a kit, or for a cheaper kit without the hot ends and motors?
