Widgets to modernise electronics in a vintage Singer sewing machine

thingiverse

These widgets can be used to retrofit an old singer sewing machine with modern electronics whilst fitting in the old motors housing. The screwdriver mount will fit around a cheap cordless screwdriver and allow it to fit in the housing snugly. The shaft diameter increaser fits within a small section of aluminium tube (to prevent wear on the plastic), and over the shaft of the screwdriver. It's locked in place with an allen key (cut flush) that fits as if it were a screwdriver bit and locks into this plastic widget.
