Overview

Boomy The Boombox

For AdaBox subscribers, in each Adabox you'll find super awesome Adafruit Collectible pin. In AdaBox 004, it's Boomy The Boombox. Now you can make boomy into an actual enclosure with 3D printing! Boomy is a super cool boombox that likes good vibrations and enjoys beat boxing. Boomy loves playing music and likes to reminisce about 1980's culture.

From Wikipedia

The first boombox was developed by the inventor of the audio compact cassette, Philips of the Netherlands. Their first 'Radiorecorder' was released in 1966. The Philips innovation was the first time that radio broadcasts could be recorded onto cassette tapes without the cables or microphones...

3D Printed Parts

All of the parts are 3D printed with FDM type 3D printers using various colored filaments. All of the parts are separated into pieces to make 3D printing easier. Assembly is pretty easy and straight forward. Use the link below to download the STLs files.

Enclosure Design

Boomy can house a number of different enclosures, not just stuff from AdaBox. You could use a Raspberry Pi, Adafruit Metro or anything really that fits.

Enclosure Workarea: 137mm x 72mm x 37mm

Multi-Color Parts

Boomy's face and buttons are 3D printed with different colored filaments. This can actually be done with single extruder 3D printers – dual extrusion is not required! To achieve a multi-color effect, the face and buttons are designed to be 3D printed in different gcode files.

First, we'll print only 1mm of the boomy-face.stl file using black filament. After the part has completed printing the first millimeter, we'll change the filament and load gray/silver. Then, we'll print the part starting from 1mm and stopping at 2mm. Once thats done, swap the filament out for white and resume printing the part, this time starting from 2mm and stopping at 3mm.

We're essentially stacking different colors on top of each other. In order to create separate GCODE files for your 3D printer, you'll have to setup settings in the slicing software.

Setting Up Simplify 3D

Setting up processes is easy to do in Simplify 3D. First, start add a new process by clicking on the Add button in the sidebar. Choose your 3D printer under the Select Profile dropdown. Then, goto the Advanced tab and look for the Layer Modifications section. This is where we'll tell the slicer to only print specific layers.

Setting Up Simplify 3D

Layer Modifications

Click on the checkbox for "Stop Printing at height" and type in "1.00" in the input field. This tells the slicer to only print 1mm of the boomy-face.stl file. Click OK and Prepare to Print! This will only be about 5 layers. Save out the gcode file and name it something like "boomy-face-black.gcode" that way we know which color to use.

Layer Modifications

GCODE Files

Once saved out, double-click the process to edit and go back into Advanced > Layer Modifications. This time, check "Start printing at height" and type in "1.00". Leave the "Stop Printing at height" option checked and type in "2.00" in the input field. Click OK and Prepare to Print! You should see boomy's facial features like the eyes and mouth. Here we'll telling the slicer to start printing at 1mm height and stopping at 2mm. Save out the gcode file and name it something like "boomy-face-gray.gcode".

GCODE Files

Once saved out, double-click the process to edit and go back into Advanced > Layer Modifications. This time, check "Start printing at height" and type in "1.00". Leave the "Stop Printing at height" option checked and type in "2.00" in the input field. Click OK and Prepare to Print! You should see boomy's facial features like the eyes and mouth. Here we'll telling the slicer to start printing at 1mm height and stopping at 2mm. Save out the gcode file and name it something like "boomy-face-gray.gcode".

Next, we'll edit the process once again, going to Advanced > Layer Modifications. Under "Start printing at height" type in "2.0" and uncheck "Stop Printing at height". Click OK and Prepare to Print! We should only see two circles – These are the outer rings on Boomy's eyes. Save out the gcode file and name it something like "boomy-face-white.gcode".

You should be left with 3 separate gcode files named accordingly. Let's get ready to 3D print!

Let

Printing GCODE files

Save the files to your SD Card. We'll need to print the gcode files in the correct order, starting with black, then gray and lastly white.

Start by load your 3D printer with black colored filament. Select the "black.gcode" file on your 3D printer and print the part. Once it's done, DO NOT REMOVE the part!! You must leave the part on your 3D printer.

Proceed to change the filament to a gray/silver colored filament. Make sure to purge the filament so it's finally transitioned to the new color. Load up the "gray.gocde" file and print it. Make sure to babysit the first layer, checking to see if the printer head is printing on top of the part. Once it's done, make sure you DO NOT REMOVE the part!!

Repeating the process, swap out the gray/silver for some white filament. Now we can run the last file "white.gcode". Once it's done we can safely remove the part from the bed. And thats pretty much it!

Boomy's Buttons

The buttons that go on top of boomy's head are printed in a similar fashion – But, we only need black and gray colored filaments. So we'll end up with just two gcode files for the buttons.

For the first part, we'll use black filament. In the process, set "Stop Print at height" to "7.0" mm. Save out the gcode and name it "boomy-button-black.gcode".

We'll use gray/silver filament for the second part. In the process, set "Start Print at height" to "7.0" mm and uncheck "Stop Print at height". Save out the gcode and name it "boomy-button-gray.gcode".

Repeat the same process like we did for boomy's face. Remember to keep the part on the bed when you finish printing the first gcode. Sad to admit but I actually removed the part before printing the second gcode – It's somewhat of a bad habit of mine :-)

Assembly

Install Breadboard

Peel back the protective film from the breadboard and stick it to the cover with the side that has the inset lip. Use the photo to reference best placement.

Install Breadboard

Attaching Handle

You'll need to secure the handle to the box using machine screws. Start by placing the handle onto the box. On one of the the sides you'll see two indentation. Insert the ends of the handle on to the indentations. From the inside of the box, you need to install screws into the holes. Fasten a #4-40 3/8" (M3 x 10mm) screws into each hole while holding the handle in place.

Attaching Handle

Install Grip

Press the grip onto the handle until it clips in place. The handle is symmetrical, so it doesn't matter which side it goes on. Note, you'll have one of the four sides exposed, so make sure it's placed face up. The grip has little nubs on each end that grab onto the sides of the handle.

Install Grip

Add Buttons

Secure the buttons to the box using glue or double-sided tape. The body and gray framing should be facing the side of the box with the flat bottom. Position the buttons center before letting the glue or tape set.

Add Buttons

Attach Face

You'll need to secure the face to the box using glue or double-sided tape. I used nitto tape because it's pretty strong but can still be removed. The face should be oriented so the handle is face up. The face attaches to the side of the box with the flat bottom.

Attach Face

 

Pro Tip: If the corners of the part are warped, you can flatten them out by carefully applying heat using hot air gun (at low temperature). Be very careful not to over heat!! Lightly heat up the corner and gently bend it to shape using a flat edge like a ruler or table.

Install Components

Now you can install your components! You can do this however you like. If you wanted to use screws, you could drill through the plastic cover and install standoffs. The half-size breadboards have a peel-away sticky backing that you can use. You could also mount components to the side of the box.

Install Speaker

Insert the speaker into the box and place it on the side with the oval shaped cut out. Install it at an angle and press until it's flush with the surface.

Install Speaker

Snap Cover

Once the components are install, it's time to close up the box! Carefully press the cover onto the box until the lip snaps and locks onto the edge of the case. Be sure to route any necessary cables through the side with the opening – Use a micro USB cable to power the Adafruit Feather and other components.
