Tosa Tool Plate Plugs

thingiverse

One of the best investments i made for my mill was a tool plate. On the upside it is great for quick change and setups, on the downside each of the holes collect chips and makes cleaning up a huge issue. You can buy plugs and screws but outside of cost i did not want to have to unscrew each time. Then John Saunders on NYC CYC came out with a video with magnet based plugs for both the pin holes and screw whole. Great idea. I could not wait and i had a 3d Printer so what the hell i want to print for plugs 4 days in a row. The next problem was what metal can i use to attarct the magnet to pull the plugs. Solution 1/4-20 1.5" steal flat head screws, they are cheap and have a black oxide coating to protect them from rusting. For my tools plate i need to print about 170 screw hole plugs and 190 pin plugs. I bought 4 100x bags of screws from BoltDepot.com. Tosa sells their very nice Delrin set for $200+, i was able to make them for under $40. I also created a mushroom shaped handle that happened to fit from 1/4" magnets I have so i have included that here. I suspect you will have to make your own magnet handle. Note: Sizing, these models are created from the measurements i took from my Tosa Tool Plate. I had to then print a little undersized to get a good slip fit. For me using PETG that say 97.5%
