Slot car copper tape tool

This is an essential tool to lay the copper tape to your wood track.
The design is based on the copper foil roll with self adhesive backing 0,025mm (0,001") thick
It is recommended to use transparent PLA to be able to see the laying process of the track tape.
Beside the copper foil you will need an M4 screw of 20 mm length, 2 washers and 3 M4 nuts.
For the guiding of the tool into the slot of the track you will need 2 pins of 3/32" of steel of 10 mm approx length.
