3D printer enclosure with automatic fire extinguisher

I decided to build an enclosure which has a separate dry space for feeding the filament, and has an automatic fire extinguisher which will fill the printer space with powder if it reaches 79 celsius (174 in freedom units). The filament is fed through the floor of the upper cabinet via PTFE tubes directly to the printer.

The lights and the power to the printer is controlled through remote electric plugs so I can turn them on from the sofa. The lights in the filament cabinet can be turned on/off separately so those are not on when not needed. On side of the cabinet there is a RaspberryPi which runs OctoPrint to control the printer remotely and send the webcam feed.

Nicely tucked away in my basement.
The printer fits nicely inside and is resting on a heavy duty rubber mat. The webcam mount is a custom design of mine.
An automatic fire extinguisher which will fill the enclosure with powder if it reaches 79c.
The upper cabinet has a latch and a rubber seal all around.
The filament holders are a remix of an existing design.
The upper cabinet lights can be controlled both manually and also through a Hue power plug.
RaspberryPi runs OctoPrint and controls the printer remotely.
With the door closed, the internal temperature raises to approximately 35c. This is too high for PLA, so I usually print PLA with the door open. I don’t get heatcreep and filament melting in the bowden tube.
Overall it is a very pleasant setup to work with.

Silfer Works Cap

As my son’s teddy got a fancy sombrero, I thought that now was my turn to get a hat! I got new maker’s marks laser engraved (I will post about these soon!), so I wanted to test the larger one on a small project. I don’t have a cap for…

Slat holders for Ikea LINDBÅDEN

While I was working on the Triple Bunk Bed project, I bought some bed slats from Ikea. I didn’t want to take a risk that one of the kids would kick the bed above and the slats would move and possibly fall down, so I modelled and 3D printed holders…

Top hat in red leather

Yet another birthday present, this time for my big brother. He has a round birthday and I had to come up with something to give to a man that doesn’t need anything. But does he really have everything? No. He doesn’t have a red top hat! He is playing the…
