Parametric wrench (any bolt shape, any size)

thingiverse

Designed a parametric wrench to be used with any bolt shape and any bolt size. By bolt size, I refer to the bolt diameter. Not sure if it's the proper term. There are 6 variables you can tweak (see header .scad file) 1. <b> socket_size </b>. is the diameter of the bolt 2. <b> wrench_height </b> is the height of the wrench (i.e. how 3. <b> wrench_strength </b> is a parameter that controls the strength of the wrench. Incease it if you need to put a lot of force on the wrench. 4. <b> tolerance </b> some tolerance to be sure that the wrench fits the bolt. You shouldn't modify it but, be free to. 5. <b> handle_length </b> is the length of the handle (not the whole wrench) 6 <b>n </b> is the number of sides the bolt polygon shape has To increase strength, I suggest using a combination of wrench_strength and wrench_height. You can also increase the infill but, in my opinion, 20% infill is good, 40% is ok but anything above 40% is a waste of material.
