Do you hate double pointed needles? Stave off the inevitable with these short circular needles. The needle portion is curved to allow you to knit comfortably with a very short overall length. I've posted two needle sizes (5mm and 6mm) and two overall lengths (230mm and 285mm) . On the 230mm length set, I can easily do 30 stitches and maybe even get down to 25. Let me know if you have another size you'd like and I'll add to the collection.
UPDATE: I've beefed up the connecting cord - it is a little stiffer (and a lot stronger) but still fairly natural to knit with.
These need to be sanded smooth to keep the yarn running over them easily. I sanded mine from 220 grit up to 600 grit and then buffed them. (Buffing isn't really necessary.)
I printed mine with PLA - the connecting cord seems durable enough but I would avoid any sharp bends. ABS or PETG would probably be a more forgiving choice of filament.
