[Elecraft] Microphone Jack Cover

[David Christ]

Sorry you felt it was unduly negative.  Written language is poor at transmitting nuance.  If I had such a printer I might consider making a cover.  But I don’t and I too  live in a less populated area and the closest person I know who has a printer is in Arizona.  I am long retired and soon will need to be moving out of my house.  I have no professional reason to support the purchase of a 3D printer and before long I would be needing to get rid of it anyway.  So for me the obvious choice is to buy a cover.  And I prefer chrome anyway.

I think my question of why is legitimate and was answered satisfactorily by W0EB in a private email.  I will admit that my comment on 3D printers may have seemed a bit harsh.  However, I don’t see them as common as he does (it would be interesting to know what percentage of hams have one) and examining my own life, short of having a business that supports one, I find it hard to see the economic value for the average ham to have one.  My lack of Ideas does not mean there are not compelling uses.  In fact I would love to hear from other hams as to how they have found a 3D printer useful especially for problems for which no other solution is available.

Again sorry if you felt offended.

Peace

It’s always here and always available, I always have filament for it, and it can produce a cap much faster than getting one shipped to me since I live rurally and there’s nowhere local to buy one. Why shouldn’t I simply print one since I already have the printer?
