Micro Hdd Servo Dimension

Hello everyone.

Can someone confirm the physical size of the Micro HDD Servo?

The product page lists - Width 3.0 cm Length 3.0 cm Height 1.0 cm which seems odd.

I wanted to make a cad file of it so. Also if anyone has done this please pass it along.

Thanks Tony

@nallycat... Again the OP wants the dimensions of the micro HDD servo not the regular full sized HDD servo in which you are measuring...
