circuit board standoff
thingiverse
Standoff designed for 3mm holes where the printed post was melted by a soldering iron. The attached STL is of no use unless you happen to have the same circuit board. The point of this post is that you can build a standoff to what ever suits your board then design the posts to 2.5mm diameter and 4mm high. Then position the board on the posts and melt the posts down to the board with a soldering iron.
