Splicing blocks are useful for salvaging damaged cassette tapes by facilitating the removal of damaged sections. There are a few types of block still available new, but most of them lack some features like clamps for holding the ends of the section to be spliced and an adhesive tape dropper to help position it more easily and accurately.
This project uses one M3 x 20 screw with matching nylock nut. A small piece of thick felt or polar fleece will be required to cushion the clamps.
This second version makes use of the precision of resin printers and does away with the need for metal springs, which some people have found hard to source. It also has improved clamps that operate by pressing down on them rather than backwards as in the previous design. The guide on the dropper has been improved to position the adhesive tape more easily.
FDM printers might not print the plastic spring properly and parts probably require sanding to get them to fit properly. Scaling might be required to increase the width of the tape groove.
