Icom HM-151 Microphone Clip

Icom likes to play it a bit fast and loose when it comes to standards.  Normally when someone complains about this digital radio is usually the subject of the conversation.  Not today folks.  That’s right, I’m ignoring proprietary codecs today because I made a retaining clip for my IC-7000.

I love this radio and have had it in my daily driver for about 3 years now.  It’s been used for net control at a race, listening to CB, and boring repeater chatter too.  I’m not sure if in my haste to unwrap it when it first came or if it never came with, but I never had a retaining clip for the HM-151 mic that comes with.  Now normally losing a mic clip wouldn’t be a problem.  When I wanted a new one for my FTM-350R that’s in my rallycross car I just went on ebay and picked up a new one for less than a buck.  With Icom skirting around typical design standards for the stupid little clips that was not an option.

So, 3D printing to the rescue!  I opened up Fusion 360 and my faithful caliper and in about 15 minutes drew up this:

Mic Clip Model

From there I took the STL and printed one out.  Making sure to print the object at at 15 degree angle to make sure the sheer forces weren’t all in the same line, I got this!

A cute little clip indeed.  So with a 1″ square of double sided tape I hung it on my car right by the map light and away I go.  (I’d get a picture of that too but it is too dark.)

If you’re interested in making one yourself, here it is!

  1. Thank You !
    I bought my IC-7000 used an either didn’t get a clip or lost it.
    I thought about designing one myself and printing it out but just a little search and
    here it is.. Thanks..
    Did you ever think about putting it on Thingiverse so it can be found a little easier?

  2. Thanks again:

    Printed a couple of these out today.. PLA 190 degs Solid infill. Plenty springy and seems to
    be strong enough.

    Printed with the tang pointing sideways so the tang layers would be a continuous line of plastic.
    I had printed a plastic remote control antenna cover (duck) vertically and found it was easy
    to snap as there are finite lines between layers.. Could have been my temp was too low on that though.

      My pleasure! Glad someone finds them useful.

      I warn you though that PLA is never great in cars. Even my nice ABS one failed. I printed a new one in nylon about 8 months ago though, and despite the problems getting it to stick, it’s been working like a champ!
