Drill Bit Set Box 1-10mm

My own box - Drill Bit Set 1mm-10mm - with gears - synchronous opening via gears

I think that for better printing of gears, use a lower layer height when printing (my print on the pictures was printed with 0.2 layer high)

there are smaller and larger holes and everything is in place and not interchangeable

gear parts require the use of printing supports
