This is a set of metric spanners that can be printed out.
The original Alibre Design files are attached. By modifying the parameters you can create any size you desire.

  • light duty = thin, solid tools
  • medium duty = thick, hollow tools
  • heavy duty = thick, solid tools


  • rounded edges where the hand may touch
  • slanted edges for the nut
  • size is +0.1mm (M8=8.1mm side length)


The STL are checked with Netfabb and should be fine.

  • I uploaded repaired versions of the medium-duty variants
  • When exporting your own from Alibre, run Netfabb on it with auto-fixing and then "close all holes". This solves an issue betwen these STL and Skeinforge 2010-02-12 .

Parametric Wrench in OpenSCAD


It's also 7 month newer then this old thing.

Yet you still spammed his page with a link to your wrenches here?

Marcus, thanks for the rating on my object. I have returned the favor.

A completely configurable openscad wrench available here: http://www.thingiverse.com/thing:4137http://www.thingiverse.com/thi... (not a derivative of this).

While Marcus may have perfected the wrench in alibre design, there is now an openscad version.

So for an M8 7,972mm should have been enough?
Given the tolerances involved on printer and nut -side I guess 8.1 is safe.
As long as it
´s balow 12,73mm it will work.
