On Amiga34 I was asked more than once to release the object file of the MorphOS signs.
Well, I admit it is kind of a cheap and simple design done in a few minutes, but I understand that without any CAD knowledge it hard to reproduce.
So here it is. The dimensions are 65 by 20 millimeter. That way it allowed me to print 10 at a time with proper spacing, but since it is a 3d vector file you can scale it up or down to any size you like. This can be done in your favorite slicer software. You may have seen the bigger version on my Efika case. It is just an up scaled version of this file.
Of course only ment for private and not for commercial use.
Note: If you are not into 3d Printing and want to look at the file, you can use blender on MorphOS or any other platform to display it. The design was made using FreeCAD. The Font is "ITC Kabel Std Bold"
