Summary The intended design of the stool is to allow better grip better design shape for a 12cm powerful fan putting under the machine, bringing down the temperature of X & Z Axis Steppers at operating temp 39deg, thereby prolonging lifespan from overheating temps of 60-80deg. You may alter position of the centre hole pin prior to your fan thickness. 

I will attach a next new advance design for the Y-Axis Fan for the temp reduction support as tested and measured. My target criteria & goal for every design is simplicity, unique ergonomic design, least filament material used, reinforced structural schemes, elimination of additional complex modules even with screws or bearings if possible. 

If you like the design and you would like to donate as an appreciation, you can paypal any amount to [email protected] for supporting my continual research test materials. Hope you all like it!
