Scriber

Scriber is really helpful in layout especially when working with metals and acrylic.I could have bought one but i decided to make something that looks fancy rather than boring generic one.
I was wondering what to design it around and I had the light saber stl ideabulb. I think this is the one (http://www.thingiverse.com/thing:799261) cleaned up the stl reduced the facets and designed it in fusion 360. I made another knurled scriber that is more ergonomic to me than the light saber one but both work the same :)
I have used sewing needles for the metal ends. I had heated it up and dipped it in oil.("heat treament")
The light saber has a hole of 2.5mm for bigger needles and the other scriber has a holes of 2mm. I had epoxied the needles in place. Designed it for press fit which works really fine. If yours is loose wrap it with PTFE tape and push it in :)
I have scribed more than 100 lines in metal and the needle is still sharp so I epoxied it permanently rather than making it removable. And even if the needle breaks I can print em again. So you decide whether you wanna press fit or epoxy.
Thanks for checking it out. Hope it comes in handy for you :)
Comment if you liked it and if you have ideas for any other tool let me know.
P.S : The metal caliper like thingy is called a Firm Joint Jenny Caliper ;) Also It would be really cool to print it in metal or wood PLA. I cant afford them for now. But i feel it would look cool :)
