This make takes on the challenge of creating an enclosure for our Bluetooth ‎Amplifier Kit, and making it look cool! This stacked Concert amplifier-style ‎enclosure will bring a little Rock ’n’ Roll to your space in a neat, rechargeable ‎package!‎

Follow along with Emma's excellent instructions and build your own. As always, the ‎DXF required for this make is shared below.‎

We Have Used:‎

  • This DXF file
  • ‎1 x PERSPEX® Sweet Pastels Orange Fizz Sheet
  • ‎1 x Maple Veneer Sheet
  • ‎1 x Black Painted MDF Sheet
  • ‎1 x Black HIPS Sheet
  • ‎1 x Black on White Laser Laminate Sheet
  • ‎1 x Gold Metalgraph Laminate Sheet
  • ‎1 x Bluetooth Amplifier Kit
  • ‎24 x 6mm M3 Pan Head Screws
  • ‎4 x 16mm M3 Pan Head Screws
  • ‎12 x M3 Hex Nuts
  • ‎8 x 8mm Plastic Spacers
  • ‎4 x Rubber Feet
  • Laser Cutter
  • Superglue or Plastic Weld
  • Wood Glue‎ ‎

How We Made It:‎

STEP 1 - DOWNLOAD AND VIEW THE DXF:‎

Check out the DXF! This one is complex, so the below image is a diagram ‎explaining the different pieces of the enclosure.‎‎ ‎

STEP 2 - TO THE LASER CUTTER:

cutter_2

Laser cut the design! The speaker grills can be delicate so make sure you take ‎care when cutting them and test the cut first.‎‎

STEP 3 - AFFIX THE AMPLIFIER PCB:‎

affix_3

Take the Base piece (the orange acrylic piece with four unevenly spaced screw ‎holes) and screw the PCB onto it, using four 8mm plastic spacers with a 6mm M3 ‎Pan Head screw at either end.‎‎ ‎

STEP 4 - ATTACH THE SPEAKERS:‎

attach_4

Screw the speakers onto the back of the two pieces with circular holes using 6mm ‎M3 PanHead Screws and Hex Nuts.‎‎ ‎

STEP 5 - THE SERVICE HATCH:‎

hatch_5

In order to make the service hatch usable, we will be encapsulating four hex nuts ‎within two layers behind the hatch. Glue the spacer with the hexagonal holes onto ‎the back of the main panel first, then insert the Hex Nut and glue the second piece ‎with smaller holes on top. Make sure they are aligned accurately! Then, once dry, ‎the front panel can be placed on, and screws used to hold it in place.‎‎ ‎

STEP 6 - ORANGE & BLACK:‎

step6_6

Take the top of the orange amplifier, and the bottom of the black one, and attach ‎them together with 8mm spacers and a 6mm pan-head M3 screw on either side.‎‎ ‎

STEP 7 - UPPER AMPLIFIER ASSEMBLY:‎

upper_7

Assemble the upper amplifier on top of the panels you attached together with ‎spacers in step6, using a material-appropriate glue to secure the finger joints. ‎Make sure to feed the speaker wire down through the holes in the middle panels.‎‎ ‎

STEP 8 - LOWER AMPLIFIER ASSEMBLY:‎

lower_8

Assemble the lower amplifier halfway, making sure to plug in the speaker when you ‎do. Then glue together the layers of the battery holder in the manner shown in the ‎images below. Put the battery into the holder, then carefully glue the back of the ‎holder to the wall of the amplifier. Make sure to plug in the battery!‎‎ ‎

STEP 9 - BUTTONING UP THE BACK:‎

back_9

Put the last panels on the lower amplifier, finishing with the back panel, using a ‎material appropriate adhesive to secure the finger joints.‎‎ ‎

STEP 10 - BUTTONING UP THE FRONT:‎

front_10

Glue the front layers together, in the order shown in the images. Then, glue the ‎decorative front sections on to the amplifiers.‎‎ ‎

STEP 11 - HAPPY FEET:‎

Now you’re almost done, and to finalise the make we have used some rubber feet ‎to stabilise the amplifiers. Add those on, and you’re done!‎
