Filament Counter Bracket

A bracket to hold a standard fishing line depth gauge to measure the amount of filamnet used.
The counter is available at any fishing tackle shop and normally attaches to the fishing rod, the line then passes thru the wheel and as the line is let out the wheel turns and moves the mechanical counter.
This counter is a simple mechanical device and measure in metres.
To adapt to your Ender 3 simply run the filament thru the wheel as shown, the extended bar keeps a slight tension on the filament on the wheel of the counter to enable it to rotate, thus counting the metres of filament used
