Stackable Featherboard with Replaceable Heads

I really like the replaceable head design from Featherboard with Replaceable Heads (m6) but some parts of the original don't work that well for me. Therefore I changed the design to accept 5/16" nuts and bolts and optimize it for Dewalt table saw 7491.What to print?1 of Main partmain_body_5_16.stlSupport not needed1 of Miter bar for t-slotIf your table saw is Dewalt, print miter_t_slot_5_16_dewalt_7491.stl. I think it'll fit other Dewalt table saws as well but I have no way to verify.You can use miter_t_slot_5_16_dewalt_7491_test_print.stl to quickly verify whether it works for you before you print the whole bar.For others, you can check if miter_t_slot_5_16.stl (changed based on the original model) meets your needs. I didn't print this one so if it doesn't fit, there's other miter bar models available here or on other websites.Support might be needed to get cleaner hex head holes.2 of Knobknob_5_16.stlI didn't print this model since I already have 5/16" star knobs from my previous pro
