Polaris 280 Swing Axle

thingiverse

Its a replacement part for a Polaris 280 pool cleaner. Being reasonably inexpensive isn't much help when you need it now instead of later. There are two versions available - one with a 6-32 brass insert like OEM and another with just a small hole to thread a stainless 6-32 screw into. You'll probably have to drill it out to get the correct size, as small holes usually print undersized anyway. I ended up running a 5/16-18 tap through mine instead of printing it again with different settings, which gave me threads exactly like the model. Keep in mind that the model is accurate and doesn't account for any discrepancies with the printer's accuracy. I printed mine in PETG, but nylon would work fine and ABS might be okay if you're just buying some time. I hope this saves someone the trouble of driving all over town to buy an overpriced part from a pool store!
