PROJECT 2: 3D PRINTER ENCLOSURE
So I decided to make an enclosure for my 3d printer (mp select mini). After researching for a while the most affordable and possibly the easiest way to build an enclosure for my mini is the Lack table from Ikea method. There is a tutorial on how to make one on instructables.com but i did not go that route but instead. I designed my own enclosure. Now the number one problem that i have with this printer is noise. I live in a very small space so I'd like to get some sleep and still be able to print/design. The most popular reason why people want to go with this enclosure is heat. An enclosure is very ideal for printing ABS .
My enclosur consists of 2 Ikea Lack tables stack on top of each others. I glued the legs to the top of the bottom table and drill a hole to insert a pin between the legs. You can easily print out your own pins. For me I was using the pins I bought from Lowes.
The next step is to enclose four sides somehow. Thats when I bought 1 piece of 18x24 arcrylic sheet and cut it to size for my front door. On the sides I bought 3 pieces of congugated plastic because they ar super cheap and they get the job done. Then I cut them to size and glued them on the sides of the top table.
The next step is attaching noise insulation foams. These foams ar designed to absorb some of the soud energy therefore reduce the noise level. Probably not by much but good enough for me.
After that I drilled a hole in th back to feed the power cable through and voila. You have your enclosure. It looks pretty neat. It does make me feel like it's a chamber. Maybe I'll call it the mini chamber.
For the glass door you can print out a latch and attach it to the sides. Itl work pretty well too. You can stop here but since I have a couple of electronic sitting around. I decided to pimp it. :))
Heres what it looks like with the electronics
The Control box consists of 1 Arduino Uno (Micro controller), 1 TFT Touchscreen Display, 1 Battery pack (9.6V RC) battery, this one is Lithium Nickel I think. And a LM298 Motor Driver. All of these components are spare since I've upgraded my RC project I no longer need these. And I did not want to throw it away either. I mainly use the motor driver for that 5V regulator. There are 2 voltage sources on the side leaving room for improvement in the future. You do not have to use it. Yo u can just use a 5V regulator and it should be good. The Neopixel and the Arduino combine I think draw less than half of an Amp. So your IC chip should be enough to supply for these.
The LOADS:
There are 2 loads. 1 is the Neopixel Ring from Adafruit. which is super colorful and super fun to play with. Costs only about $10.
The other load is the temperture sensor from ebay. This guy is also very affordable. The name is DHT11 Sensor. There is a library for it for Arduino so it was super easy to work with. And the temperature reading is quite accurate.
Okay.
So here is the code for the arduino
