Man, this is a cliche thing to print, but it is really useful. Thats a picture of it on my Amscope 10-30x scope. Now that I have the dimensions down, I am going to re-print it with a rest for my phone. I would provide the model, but it was actually 5% “too small” although it could be that the printer just printed it a little small-I need to check the calibration and see how close it is.
You can see here how I trimmed the length a bit too, since I didn’t know how long it should be. I just used some flush cutters to start the removal, and then the layers peeled off from the Z axis. Its kind of an adjustable length print, since the walls are just two layers thick.
Anyway, the results are great! This was taken at 10x, and you can probably already see why it is easier to solder through a ‘scope than with just your eyes. And sometimes you need to get tiny, so that is what 30x mode is for.
