I attended the Kootenai Amateur Radio Society meeting on Monday to present my portable ham radio desk stands to the group. I met with enthusiastic support, but there were requests for stands for other models I have not explored. I will do that exploring. I gave out some cards, so several of the members may call me to request a stand.


I very reluctantly got a Facebook account when I got my Creality CR-10 3D printer, as that was the only web site that had support for the printer. I now find that it is also the only web site that has support for my Essential PH-1 cell phone. Facebook's major problem is they want a cell phone number from me for no particular reason I can see. They call it a 'security measure'. How is it secure that my cell phone number is out in public like that? And easily obtainable by unscrupulous individuals? I will not give them my number, but that means I can no longer get to either of those web sites. I will be objecting to this, but not to Facebook, who appears to do whatever they want (just like PayPal). I notified the CR-10 web site moderator, as I knew his name and YouTube channel. I can't notify the moderator for Essential, though.

Frank Fleming, another Phuddy Duddy Cruisers car club member, passed away last week. My condolences to Linda, his wife. Frank and Linda were active members and they owned a 1948 Dodge truck, 1951 Plymouth Cranbrook and a 1946 Chrysler. Frank will be missed.

That makes two members this year and at least two members last year. We need new young members so our club will not fade away.


I have pursued a manufacturing solution to the ham radio desk stands. I contacted Accurate Molded Plastics in Coeur d'Alene and gave them the model files for the three different stands. It turns out that they could not read the files using their SolidWorks CAD program. Those files were directly created by TinkerCAD.

In order to give them something to use, I installed FreeCAD on my computer and downloaded the three models from TinkerCAD as .obj (mesh) files. I then used FreeCAD's mesh analysis and repair to fix the models. I saved them as .step files, which is a native format for SolidWorks.

After they got the fixed models, it took AMP a day to generate a quote for me. That was not good news. They quoted $15,250 per mold ($47,750 total) and they charge $7.04 per unit for quantity 50 ($1,056 for all 3) or $4.04 for quantity 500 ($6,060 for all 3). No matter how you look at that, it is way, way outside my resources. I am currently selling these at $4 and I would have to sell the 150 models for at least $325 to recoup my costs. Whew! No commercial deal for these...

Since it is getting to be the end of the year, and all my toys have been put up for the winter, I am doing web site maintenance. First up is to back up the five web sites I maintain. That is literally gigabutes of information to download, so it will take quite a while.

I will then look into updating the web site layouts. A couple of years with one layout is probably enough.


This is the final desk stand of the three I have designed, printed and sold. As you can see from the picture, this one is for the Tytera MD-380 ham radio.

At a suggestion from one of the hams, I have added a couple of holes to the stands, so they may be screwed down to a bench if necessary.

I am now looking for someone to manufacture my designs, as they seem to be quite popular. Apparently, there is an injection molding place in the Coeur d'Alene Industrial Park, so I will try that as a start.

I have finished designing the desk stand for Baofeng UV-5R portable ham radios. I removed the old cradle that had been based on the cradle for the Yaesu FT-D2 radio, and created a new cradle from scratch. I printed one and found that I had not measured the height of the cradle correctly - it was 9mm shorter than it should have been. That didn't prevent the sample cradle from working - you just couldn't hook the back of the cradle with the radio's belt hook.

I have adjusted the height and you can now see the result.

I will print a couple of these and show them and the FT-2D cradles at the KARS next meeting. They should like them as well as they did the ones I sold them for the TYT MD-380.

When I was younger, I could remember anything, whether it had happened or not; but my faculties are decaying now and soon I shall be so I cannot remember any but the things that never happened. It is sad to go to pieces like this but we all have to do it.
