Description

I've been starting to print raftless, but I was having a terrible time adjusting the M3 nuts on my HBP to get it level and flat. My needle nose pliers don't fit in my ToM well and I didn't want to keep taking the X platform off just to make small adjustments. I was about to search Amazon to find a small wrench when I realized I could make my own!

The file is parametric. Fill in the width of your nut (the STL file is set for an M3), the thickness (the wrench will be 20% thicker) and you'll get a nice wrench.

For bonus fun, you can set the size smaller and the wrench comes out pretty cute. If you set the nut diameter to something like 4.2 (which I did by accident) it looks great but is still pretty tiny.

For some reason, customizer as well as my own openscad application show just two cylinders instead of a wrench. What am I doing wrong?
I needed a M6 wrench as well as a better printed M3.

First time I used openscad :)

It would however be nice if the scad file included some comment suggestion for dimensions for other sizes than M3.
(Yes I that lazy, typing is easier than finding the calibers)

P.S. The not included shapes include file also defines the box function, not just the hexagon.
Very useful. I printed also the m4 wrench scaling your model 1.4x

OpenSCAD version of the solid version of

thingiverse.com/thing:1853

and same as

thingiverse.com/thing:4137 ?

My usual suggestion of tapering or rounding so it's not so fiddly to put it around the nut time and time again until it's fastened.
I prefer the OpenScad version so I can make the key I want with the same file ... Gppd work MBCook!
They are all parametric.
