I made a stand for my $5 lamp that I bought on Temu to hold my USB microscope. I was inspired by the connector on this user's stand, but I improved it, since its grip was too loose and it fell off very easily. So if you have the arm from that stand, you can try it to see if it works :) (The comparison images are above; if you are a user of the other stand, you can also use this arm, although I recommend extending it by 0.1 mm).

The bottom part of the ring might fray a little, but it will still hold the microscope very well (I'm new to this).

I don't have a Bambu Lab printer, so you might want to use your custom settings for this.

You don't need any kind of support to print it, but you will need to glue the piece with 4 pillars as in the following image:

(simply put the microscope stand with that piece in place and then add a little super glue)

All parts have a 1.6mm gap so you can add some double-sided tape only in one part and it won't move.

So just apply a little tape like this

and on the pins like that

I also made pins so you can guide a cable through the lamp body (photo 3)
