I have been making some experimentations with different feeder design ideas.
"Clothes pegs feeders" for example. The aluminium box is nice and the spring for holding the tape flush to the upper surface.
Wooden gang drag feeder:
Tape peeling roller is yet to come.
Also been thinking about modular 3D printable solution. Even made the following design: https://a360.co/2IXTOri
Sadly do not have acess to 3D printing at the moment so been unable to test it out in practice. It is currently meant to be used with the same metal springs but maybe possible to make the flexible 3D printed leaf spring with usual ball pen spring as extra support under it. The metal springs used are cut from metal cable tie that I found to be suitable stiffness and width.
