I was looking online for something unrelated yesterday and cam across this:
Has anybody tried this? It would seem that $200 for an Ender 3 and $350 for a conversion kit would make this one of the cheapest belt printer options on the market. I understand that there is also a conversion kit in the works for the Artillery Sidewinder, which would probably be better (larger print area and direct drive).
Still not enough for me to take the plunge yet, although I can think of a pile of specific use cases that a belt printer would be great for my uses.
