This is a stand to hold and display petropixels W16 engine http://www.thingiverse.com/thing:68806 . It holds it at either end and stops it rotating by holding it in three of the grooves at either side. There are also longer pins that come out of either end of the crankshaft which are needed to be used with the stand. I used the remixed crankshaft http://www.thingiverse.com/thing:70153 so these are the longer pins I have provided.

Simply print the W16 Stand.stl file and two of Longer Remixed Pins.stl. Insert the longer pins at either end of the crankshaft rather than the ones currently there, put the engine in the stand with the pins through the holes and reattach the handle to one of the pins. There will be a new file shortly which has the stand and two longer pins in one file for easier printing.
Does not require support, should print in less that 2 hours with a 0.2mm layer height and roughly 20% infill.
