I upgraded my Original SL1 to an SL1 Speed, and these are the leftover parts. Good spares for your SL1.

I don't remember exactly what each part is called, but what you see is what you get. Everything was in good working order when I removed it from the printer.
  • 1x aluminum Printing Platform (has visible scratches, but nothing that would affect print quality)
  • 1x aluminum Print Tank with FEP (FEP is a little cloudy, but worked fine last time I used it)
  • 1x LCD screen (spotless, like new condition)
  • 1x UV LEDs with heatsink
  • 1x reflector box for UV
  • 1x plastic fan shroud
  • 1x power supply (?) module
  • bag of misc nuts and bolts
  • 2x spare FEP (brand new)
Will bubble-wrap pack in original Prusa boxes.
