Got time to kill so...

I design and cut the various pieces to fabricate the peltier-based heat exchanger below. The black box came from a CPU cooler (water-based). It has an internal water pump and copper heatfins. Coupled to it is an aluminum heatfin with a small fan designed for a pentium CPU. The stand was cut from 4mm acrylic. The contraption works but the fan may be too small to efficiently remove the heat from the aluminum heatfin. Suitable for low power cooling... Yet to hook it up to the high speed spindle for heat removal testing...
I received a complete ER11 collet for the high speed spindle a while back. They came in individual box as shown in picture below. I decided to make a simple holder for it and engraved the lettering for easy identification and storing.
The holder in a plastic 'drawer' ready for slotting into the wall mounted chest. The 6.0mm hole is empty since the collet is in the spindle...
