Neiko center hole punch TPU cap
Description
I have a few hammering center punches that i use. but i always wanted and automatic one that you just press. i recently got one as a present - the Neiko 5" one ( https://amzn.to/2XOMVvQ ). it has adjustable pressure and is made out of pretty good steel (i have already used it on a few metallic surfaces). i carry my center punches either in my makita drill case or in my toolcase drawers. in either case i need them to have caps. i used to use a cork screw with a hole drilled, but those needed a replacement after a while. they can also fall off on their own in the drill case. making one out of TPU was a small matter of measuring and revolving. as an added bonus it snaps on and will not fall off. the model is available as gpl 2.0 opensource (meaning if you make a change, you post your source as well) on fusion360 ( https://a360.co/2vuSiUI ) and as a .step file.
