Currently operating with Anycubic Kossel Plus - my first printer ever. Chose delta printer despite warnings from friends because they were selling for unimaginably cheap price during last years November ($160).
I later learned out that the reason they were sold for so cheap because Anycubic seems to be phasing them out, and is no longer selling them in their own store.
It is running 100% on stock electronics, I have printed all the orange parts you can see as modifications to it for various reasons (support, fixes to issues)
I've been relatively happy with it, printers own sticker-bed was ruined in a week after purchasing, and had to swap to coated PEI from Energetic. Print Quality is bit of a hit and miss sometimes. Overhangs are the greatest difficulty in its default configuration, cooling isn't the greatest even with newly-printed part fan duct.
I have had to move the mainboard away from its default position, as it was too close to the heated bed (directly underneath it) which was causing overheating. So I printed the feet you can see and got board away from the heatbed to prevent that from happening.
Another fix has been the 3 orange arms you can see holding the "umbilical cord" leading to hotend, during tall prints there is a issue where the cord would be hitting prints and sometimes ruining them. The arms holding the cable solved this :)
On the right side of the printer you can see Polybox from Polymaker, it's a filament drying box & spool holder which I got for christmas. It has battery-operated sensors for measuring humidity inside the container, and drying is done passively with drying packs inside the box. So naturally you need to buy new silica/reusable ones if you want to keep this box in operation. Simple but works great, doesn't waste electricity either !
My most favorite recent project has been making roses for the spring, I haven't yet printed all the stems for them, but that's in the works. They look absolutely stunning!
