E3D Toolchanger.
I used it with Prusa Slicer for a while to do PETG with PLA supports, and other mixed use printing.

The toolchanger includes:

• 4 Hemera tools, direct drive
• Collection of nozzles: 0.4, 0.25, 0.6 etc
• Collection of spares: volcano hot end, thermistors, etc
• Glass print bed + extra set of textured and smooth surfaces
• Includes 2KG of white PLA filament and maybe some others.

Minor mods:

• Chamber temperature sensor
• Chamber heater (needs an enclosure ideally) - holds 60c ambient
• Accelerometer on the head for input shaping/tuning
• Enclosure with lighting and fan extraction, that also insulates noise

Duet 2 wifi + expansion board, all official parts, bought as an already hemera equipped frame. I can deliver nearby as needed.

Optional:

Could include a spare Duet 3 wifi + expansion board and electronics that I had intended to use to build a Jubilee.
Could include a microscope.

Could include the enclosure/case: it is intended to hold the printer(s) on isolated stone surfaces to absorb vibrations.The enclosure has wheels, is made from extruded profiles and glass safety side windows, from Conrad electronics. High quality.

The case can hold rolls of filament above the printer. Currently the top section is used as an enclosed resin printer space with an Elegoo Saturn 4 Ultra, curing and washing station, vented outside.

The enclosure is optional and is to be discussed separately. The resin printer is not included either.
