Summary

I designed this vent system for the WhamBam HotBox to vent fumes outmy office window, particularly when printing filaments like ABS. It uses a75mm 12V blower fan, some 1/2" ID flexible tubing, and optionally hoseclamps to help keep everything together. Temperatures in the enclosurewhen printing ABS stay around 38C-40C.

whambam hotbox vent enclosure

The idea behind my system is to allow it to broken down quickly, as theHotbox folds flat for storage. It could probably be adapted to otherenclosures as well. I've included the Fusion360 files for modification, asI've designed this to fit 1/2" ID tubing. Using 1/2" tubing restricts the fan,but gives the air enough velocity to get out the window. This waytemperatures can be maintained in the enclosure.

You'll need to purchase the following: 12V 75mm blower fan: Blower Fan

1/2" PVC Flexible tubing: 1/2" Flexible Tubing

The fan can be powered however you like, but I bought this power adapter,as I may add lighting to my enclosure: 120V AC to 12V DC Power Adapter

The hood and plate screw together in the exhaust port on top of theHotbox. Slide the fan onto the threads on top of the plate, and then thesmall nuts can be threaded on to hold the fan in place. The nozzle part willsnap fit onto the output of the fan, I'd do this before mounting the fan soas to not break the thin fan pins on top of the plate.

While not necessary, printing the threads that hold the fan on are bestdone at 100% infill. The uploaded .3mf files are modified for this. All otherparts should be fine with at least 15% infill. No supports needed, and PLAworks fine for everything. 0.15 layer height will help make the threadssmoother.

The window bars fit across the bottom, and then close the window on top.The model files are in the orientation to be placed in the window, soprinting them rotated 90 degrees so that the port for the tubing is facingup allows for printing with no supports. I print these at 0.20 layer height. Ineeded 3 solid ones in addition to the part with the hole for my window.Close the window on top of them, and fill the gaps with a piece of paper orwhatever you choose.

You can use small hose clamps to hold it all together, but I have a prettysnug fit with the 1/2" ID tubing.

Fusion360, 3MF, and STL files are included for your use. Happy printing!
