This is version 2 of this model. This version is scaled up by 200%, and the wrenches now print separately in two pieces each.

After printing my original model in silk PLA, I decided I'd like to have the skull printed in white, and the wrenches printed in the silk silver PLA. While I was chopping up the skull and splitting the wrenches, I decided I wanted the model to be larger. If you're happy with the size of the version 1 model but want to print the wrenches separately from the skull, scale both STL's down by 50% on all three axis.

At this scale, the skull portion took 8 hours for me to print. I tend to leave my walls and top & bottom thickness to 1.2mm.

UPDATE 01252022: FairPlay4 pointed out difficulties in both printing the wrenches at 50%, and with strength of the wrenches at that scale. I uploaded two less detailed versions of the wrenches titled "Alternate_Wrench.stl" and "Alternate_Wrench_50_Percent.stl". These files each contain one wrench intended to be printed horizontally, so two copies will need to be printed in either scale. The finish on the wrenches will suffer when printed in silk PLA, but they will print easily and with much better strength. If the original "Wrench_Cut_X2.stl" is too unstable to print at either scale, try the alternate files.
