Móc Treo Cưa

A hanger for any flat hand tool such as saws, squares and straight edges. 

I printed mine from PETG which is a bit slippery for the mechanism to grip things.  I solved this with a wrap of electrical tape around the roller.  You could print the roller from a flexible material if you have it, and that would work great.  Also the roller is 19mm(¾") in diameter so you could substitute in a length of wood dowel and that would probably grip well enough.

Edit:  Wine corks are another great option for the roller, reported to work well by vaderag and ironfounderson.  Also added two more roller options, one with knurled pattern which should act similar, hopefully better than the fuzzy skin option that Vaderag and  Ede.Duembel used.  The other new option is a roller with grooves for o-rings.  

The cover is held on by ether M3 screws or #4-40.  Both will self tap nicely into the holes in the main body. 

Edit 2: For those who want a fully printable option, I've added that.  The cover is held on with an interference fit by tapered dovetails.  Since the fit will depend on printer calibration I've included 4 clearance options for the cover, 0 clearance went on for me, and my printer is slightly overextruding, though it did need a hammer to get it in place. so 0.05 or 0.1mm clearance might have worked more easily.
