Adatper for Shimano 600 EX Arabesque Headset to 36mm Wrench

thingiverse

Adapter for Shimano 600 EX Arabesque Headsets to 36 mm open-end wrench. You need to print this adapter twice to be able to properly tighten the headset. Therefore, you also need two 36 mm wrenches. I do not recommend using pliers as there is a higher risk of slipping and breaking the printed apart. Each adapter is 7 mm (approx. 1/4 inch) high. You should check before printing whether there is enough clearance, especially at the lower nut (i.e. the one connected to the bearing shell). If not, scale down z-height of the adapter before printing. Note: The fitment of this adapter is not perfect. But it was good enough for me.
