Magnetic parallel holders, $15, Windsor, ON

Seems kinda gimmicky to me. As if standing a parallel up is too darn challenging......
 
Keeps them from flopping over - I think it's a good idea. 3D printed. I'm going to make some. I usually use a couple of 'springs' made from metal strapping to hold the parallels up. I have another version of this - 3d printed parallel holders for the lathe chuck.
 
3d printed parallel holder. A few magnets grips the parallel and a few more on the bottom keep it in place. You could use these on the mill vise too but I meant for them to be used as a stop on the lathe chuck.

I find that the parallel against the fixed jaw usually stays in place. The one on the movable jaw frequently falls over upon opening.

Edit: My only concern is that they'll be a chip magnet...

I save almost every bit of steel strapping that comes through the shop. That's what I use for parallel keepers. I have even ground some into actual parallels too. I want as few magnets in the shop as possible. Near chips anyway. Drives me nuts.

I might have to pause that thought, and print some like Jangers though. I like that idea. I have a couple spiders, but still like parallels sometimes though.

I missed that. I had thought you meant on a mill vise. Yes, on the lathe they make sense. Someday I'll make myself some decent spiders. It's that or make the buttons that some guys use with machine screws into the chuck face.
 
John, I like these as another pair of hands for setups in a lathe chuck – can you share the STL file(s)?


Thanks,


Charlie

slicers do use 3Dmf files. At least the prusa slicer and Bambu ones do.

Thanks: I just tried loading it and Cura seems OK with the file type, but it's too big for my Lulzbot Mini (6x6 bed). If I ask nicely could you reduce the length of the holders (pretty please)? My 3D resource is TinkerCAD, which doesn't support 3Dmf.
