Hey all! Longtime lurker, recently I stripped the hex screws on the resin vat for my Anycubic Photon Mono M5, I tried getting a cheap extractor bit from the hardware store but did not have any luck with it. Does anyone have any techniques, specific tools, or a different extractor bit that they have used on flat headed 2.0 and 2.5M hex screws to remove stripped ones?(I believe they are 2.0 2.5 off the top of my head.) THANK YOU to anyone for any advice forthcoming 😇
