I previously asked sales about this and was told there would not be a kit offering.
As such, I just went through earlier today and ordered all but two items needed to build myself both dual extruder versions (minus the hotends and any printed parts). Since I’m printing my own parts (and going to retracting printheads), there is additional value in keeping my existing PLA extruder functional in case I need to work on the dualies. You could always do the same moving only the hotend.
I had to overbuy most components due to being sold in 25/500/100 packs depending on the parts. I’d love to split up some of the multi-packs, so PM me if you’re interested. As soon as I track down these last two items, I should be able to figure out how much a set costs in small quantities.
Those two items are:
Digikey W504-100-ND (really expensive, and I don’t need 100ft – trying to find smaller quanties)
Associated Spring C0240-032-0380-M (appears to be a bad part number, or just nor searchable)
