How to print:
Print the joining box using 0.2 or 0.3mm layer height option. Slice the box and the lid in the same file. The recommendation would be to slice several boxes into the same file. This will increase the printing volume and will allow the print to cool down before the following layer.
How to use:
insert both of the chords into the box, secure them into position with some cable ties, solder the wires and then fill the box using a hot melt glue gun like in the picture. Place the lid on top of the hot molten glue and allow it to cool down.
