Replacement Knobs for Becker CDR-220 Radio

thingiverse

If your Becker CDR-220's knobs have become sticky, you can easily replace them without breaking the bank. In my case, the knobs had turned into mush and I wasn't eager to try any of the suggested fixes. A new set was definitely in order. You can buy authentic replacements directly from Becker for $40, but that seems like a pretty steep price for just two pieces of plastic. The replacement knobs aren't exact copies of the originals, so I tried printing duplicates using 3D technology. Unfortunately, the limitations of this method got in the way and I had to make some compromises to get the print right without needing any further adjustments. The result is close enough that no one will notice they're not original. These knobs may also fit other Becker radios, not just your CDR-220.
