making the mini screwdriver handle into a micro screwdriver handle was my goal as i needed to get into an extremely small space. the base part is 6mm tall but only adds 3mm to the total height of the screwdriver handle for a grand total of 15mm tall when assembled with the bit holder. (original was 32mm base, 44mm total)

it was a very tight fit and i needed to actually step on the parts to get them together.
