External Fan Housing for Bosch Rexroth

We had during summer time a lot off issues because of overheating. 

So i designed an easy Mounting Fan Housing with 24V DC Fan. Originally that equipment is passivly cooled over Steel Housing.

Once printed the cover, I tool a heat gun slightly heat up the model and once smal printed connectors to center got melted Press Flad the Cover. Then it looks like the one on Picture.

8 x Threat Inserts M3 

4 x Zylinder Pins 3 x 14mm (first glues them in case. 

4 x M3 x 10mm Stainless Steel Hex Drive Flat Head Screw

4 x M3 x 25mm Stainless Steel Hex Drive Flat Head Screw
