GMA fuse holder

thingiverse

Here's a 3D printable fuse holder designed specifically for small GMA fuses that measure 5x20mm. This design is easily printed with supports, featuring an integral spring that helps keep connections secure and tight. To create the fuse contacts, wrap a short length of 23 AWG wire (equivalent to one strand from a CAT 5 cable) twice around each end bar and twist it together to form the connection point. For optimal contact quality, use solid copper wire instead of stranded or CCA copper clad aluminum. The fuse will fit snugly into place when pressed in.
