Same here, between them #Adafruit and Newark.

Need to find a new source to have boards made.
As long as the boards are small I use Osh Park. Need to find a place for larger boards in the U.S. Anyone use Digikeys DK Red Service? Or another?

Osh park is expensive if you are doing larger boards. Is OK for a business but not a casual hobbyist.

The impeller for my pool heater failed several years ago . They did not sell the part and my attempts to glue the old one failed after a short time The temporary impeller I made with the printer is still going strong . Removed it awhile back and it looks fine.

Speaking of fixes, the air compressor I bought to inflate tires was useless as it took forever to inflate a tire. Thought it was bad so returned it and bought a new one.

Turned out its a safety feature they lower the output to the point it is useless. I took the regulator apart and figured if I redesigned one part it would allow more air to flow . 2 new o-rings to seal it and a bit of silicone lube and I’ve been inflating tires happily since. The old setup took a few minutes to bring a car tire from 28 to 32 PSI. It now does it under a minute.

I printed 2 gears for my 7x12 lathe out of a filament from Igus.

Been in use for over 5 months and from inspection are in good shape. Quieter and unlike the originals durable. One is sacrificial and will shear if the lathe jams. When I jammed it it loaded the motor pretty heavily then let go so it did work. Some replace that gear with a metal one but I wanted the sacrificial feature so I do not blow the motor and speed control.

You need a heated chamber and they recommend heat treating it before use which I did not do since I was not certain it would not change the dimensions.

They have a few other filaments that are also useful. I went to this after multiple attempts to 3d print delrin. Even made a wood bed and finally gave up.

It’s not cheap but I still have over 90% on the reel left after printing 3 gears.

I have a roll of very low temperature solder that has high bismuth content. It is not to solder with instead you use it lower the melting point of solder then wick it up . Was used at EMR Telemetry and when they were sold I was given a roll. Like a big roll of chip quik.

It is valuable to desolder things like ESP32s. The odds of lifting pads are slim with it too.

@RandomUser @Mammothmothman

Problem with doing that is sooner or later you are going to end up with piles of stuff like esp12f’s and such. I have more packaging tubes of ATtiny85’s than I will ever use.
