Tevo Control Box Air Vent System
Description
This is a cover that fits over the Tevo Tornado Control Box. The cover allows you to attach standard abs plumbing. This allows you to add fresh air venting to the Control Box and keep it in the enclosure without the Control Box overheating. when printing with an enclosure, you have to move the Control Box outside of the enclosure to prevent overheating of the Control Box. In order to do that you have to add extension cables to the Control Box wiring. This Vent design allows you to bypass all that and keep the Control Box inside the enclosure. All you need is some standard abs plumbing: 2 ---> 2" to 1 1/2" abs reducers 1----> 1 1/2" abs 90 degree elbow standard 1 1/2" abs plumbing length will depend on your enclosure. Instructions: slice with repetier-host or cura 4.0 as this is the software I used and the .stl files will scale properly in these programs. repetier-host units of measure is set to meter. make sure repetier-host units of measure is set to meter for proper scaling. 1. Print the Vent Cover 2. Print the sliding door for the usb opening on the Vent Cover The print is around 14 hours depending on your settings. I used Repetier-Host CuraEngine Set supports on and touching bed, I used support type "Lines", they were very easy to remove. Carefully remove the supports as the 2" connections on the Vent Cover are only 2mm and can break easily if treated ruff. do not glue any of the abs plumbing, so if you have to take it apart it will be easy too. attach the 2" to 1 1/2" reducers to the Vent Cover and caulk around them to seal them, you want an air tight seal, use clear caulking so it turns invisible. the caulking will also hold the fittings onto the cover, as they do not fit super tight. wait for the caulking to completely dry before continuing (12 hours) put the control box inside the enclosure, and place the vent cover over it. then attach your 1 1/2" abs plumbing & elbow. caulk around the holes in the enclosure that the abs plumbing goes through. see the picture of the Vent Cover in my enclosure. the abs plumbing can be bought at any hardware store and is cheap should be easily under 20 bucks for all the plumbing. the venting just uses the fan in the control box, the Vent Cover Lines up with the fan.
