Walkman WM-22 cassette player Prop

Description
This is a model of the Sony Walkman WM-22 for use as a prop or fidget. It features workable buttons, a rotatable volume-wheel, a miniature cassette deck, a grippy fuzzyskin-backside, a 5V DC jack and unlike our smartphones a headphone jack.
The ‘PLAY', ‘REW’ and ‘FF’-buttons are all workable. Pressing one button resets the other, while the ‘STOP’-button resets all of them. You can set the slider one the side to ‘Lock’ and prevent the ‘STOP’-button from working altogether.
To ensure elasticity, the springs need to be printed in PETG. Do not print them in PLA, they will not last long. I printed them in yellow PETG to make it easier to differentiate them from the black background.
While I tried to keep it to scale, I took some liberties in designing the model.

Parts overview
(The springs were printed in yellow to aid visibility, they will be covered, so choose any color you like) | ||
1. | Place the slider in the slot as shown.
Important! Make sure it slides smoothly front and back. Depending on the tolerances, you might need to sand a bit. | |
2. | Place the buttons slightly behind the slide.
(From left to right: FF <<, REW >> and PLAY)
Take your time, make sure the slider and the buttons align properly. | |
3. | Add the springs for the buttons.
First, push both tabs into the recess on the back of the button, then push down the back of the spring, it should snap into it's place.
Make sure the button moves without resistance and the spring is fixed in position.
| |
4. | Add the spring for the FF and REW-buttons in the same manner.
Again, make sure the button moves without resistance and the spring is fixed in position. | |
5. | Add the last spring slide by pushing it into place from above. Make sure it is properly seated in its recess.
Test the mechanism by pressing each button successively and make sure the buttons are being locked and released by the slide. It might take some time for it to move smoothly. | |
6. | The top part is pushed down on the case. |
3. Join the bottom and middle half
1. | Place the assembled middle part on the bottom.
It should fall into place, do not use force! You might need to wiggle it in place. | |
2. | Screw the two M2x2.5x14 into the parts. |
|
3. | Use the M3x8 screws and join the halfs.
(By lowering or increasing the tightness of the screws, you can adjust the resistance of the volume wheel.)
Make sure the volume wheel, the locking slider, the gears and the buttons operate smoothly. The mechanical parts should all be working by now. If there is any binding, it is easier to fix it now.

4. Lid assembly
1. | Insert the window into the backside of the lid.
Make sure the small taps on the window are seated properly. | |
2. | Insert the two 2x18 dowel pins into the inside of the hinges.
Align the lid.
Push the dowel pins into the hinge.
This is how it should look like.
|
|
3. | Insert the lid carefully into the guide.
Once it is seated, it will keep the lid open at any degree and provide an end stop. |
|
4. | This step is optional!
You can insert two 4x2 round magnets into the lid.
This will help keep the lid shut properly and honestly, makes it feel better, when opening the lid. |
|
| You should now have a almost functional Walkman! |
