Bowden Extruder for 2020 Extrusion Mount Delta

thingiverse

I desperately needed a new extruder for my trusty old FLSUN delta printer, but none of the models available suited me, so I decided to build one from scratch. My experience with flexible filaments has been positive, but this design matched the gear that came with my printer perfectly, meaning if you have a different gear, it'll need to be modified or closely match the original. In general, I've been thoroughly satisfied with how this extruder has performed. Instead of hearing a single skip, I now see colorful dust particles if anything manages to prevent it from extruding. The design is also incredibly open, making it easy to clean the gear. My gear measures 8mm in diameter with a groove that's roughly 2.8mm wide and 0.7mm deep. The bearing used is a 22mm OD by 8mm ID bearing (technically 7.9; I opted for a cheap option). The spring is 6.28mm in diameter and 12.3mm tall, with a link to the product I purchased provided below: https://smile.amazon.com/dp/B008RFGNGA/ref=cm_sw_em_r_mt_dp_U_PR-9EbRH4A87C To avoid unnecessary verbosity, if anyone knows of a good, affordable, and easily accessible gear with a groove for a remix, please let me know! I'd like to have one that I can recommend instead of simply stating "this is what came with my printer".
