Nucleo 64 Breadboard Holder

This holder is for Nucleo-64 and standard breadboards…

The Nucleo is attached with 3x M3 8mm brass spacers. To insert the spacers into the breadboardholder, heat them with a lightner and press it carfully into the breadboardholder.

So that no unnecessary gaps arise,
cut the expansion clip from breadboard.
Then you also fit into the designated opening !!!
