Standoff clips?

I recently purchased the tiny arduino package, Pro Micro - 5V/16MHz.

I would like to mount it securely and I am looking for the little standoff clippy things. The Pro Micro has no mounting holes. I’ve seen side clip standoffs before, just can’t seem to zero in on a supplier.

Thanks in advance for any tips,

Chris.

This part is close, but still expects a hole in the PCB:
