Cool looking book case for those mechanics. Printed using the CAD from the Ford Engine Block (link below). The Ford 6 cylinder engine block was printed up to height of 78mm. If you are planning to make this product stop printing at 77-80mm in height. The fan was borrowed off the Toyota Engine CAD (link below). The bookcase rings and fan axle are made by me.

The engine block was printed in Orange PLA, took 20-25 hours on the TAZ 4 at a 3mm layer height and at 120mm/s.

The fan, and bookcase ratings were also printed at 120 mm/s in a 3mm layer height. Both were printed in ABS. They only took one night.

All the parts were joined with a hot glue gun, be cautious of any fumes! Hot glue does slightly melt PLA plastic. Do this in a ventilated area with eye protection.
