Need some measurement for my sak build

[RevvRav]

Hi, New here but been lurking for a while and i'm about to build a 91mm. Could someone help me with the measurements for the base of the cybertool bit driver, height and width should do at this stage please.

Cheers

I'm not sure what you mean by base? The base of the bit holder? Inside? Outside? The base of the metal length going down to the tool? The base of the connection to the tool itself?

I've given away the Cybertool I had but I'm sure someone here can help as that is usually the case. I think it might help with a picture or drawing showing the needed measurements though. Just a suggestion.
