I did a little Googlewhacking, and found that places like the UPS Store and Staples frequently have 3d printing services these days. But if you can't find one nearby, there are online services that will print your file for you and ship it to you. The cost varies on the complexity of the piece and what material and settings you choose for it. I have a 3d printer but I'm not very good with it yet, so I keep track of where things can be printed in materials my printer won't handle.

I found this list for 2021 that seems reliable. https://all3dp.com/1/best-online-3d-printing-service-3d-print-services/

I like All3dp.com for its 3d-printing related information.

I'm wondering how smoothly a 3-d printed reduction drive would work.  Personally, I think I'd take the suggestion about buying a vernier reduction unit from somewhere.  If nothing else, it would likely look better on your rig.  I've used 10-turn pots before with good success, if you have room inside your case for one.
Good luck and 72,

Most of us have built small rigs with potentiometer/polyvaricon tuning that was horrendously fast and awkward.   I am in such a dilemma with a little homebuilt rig that I love but it's waay too twitchy on the  tuning.   I've been searching around for an answer and think I've found it in a reduction drive tuning knob.  Something like this. https://www.thingiverse.com/thing:3562490      Problem is that it's 3D printed and I dont have the knowledge, or the equipment, to produce one.  So I'm wondering if a member of the Group can produce one for me.  If so, pse contact me via email directly.

I could cut down the tuning range (and still stay centered) with series caps on either side of the polyvaricon, but want to be able to use nearly all of the CW portion of the band (80M) - but more slowly. 

TIA, really appreciate any help.

Second Sunday Sprint

John Lonigro
 

Don't forget this Sunday is the March edition of the Second Sunday Sprint.  Since Sunday is the 1st day of Daylight Saving Time, I will remind you that this contest's LOCAL time is not changing.  It will still be 7:00 - 9:00 pm central time.  But that is now CDT, not CST.  If you go by UTC, the sprint time will now be 0000-0200Z Monday.  Over the winter, it was 0100-0300Z.

Hope I didn't confuse anyone.
