So the first round of fuses are printed and a quick round of resistance measured with each. 

The printing was successful, but done "with brim" to help keep them in place. That said, I am not sure that was necessary, it had been a while since I had used the conductive PLA and I forgot how great the bed adhesion is, it sticks well, really well. So the next round will probably be without brim since the thinner fuses are difficult to separate from the brim without breaking, that and they get a weird flat spot from the brim.

Another note on printing, the fuses need printed horizontal, the conductivity between layers is not as good as within layers, so unless greater resistance is needed stick with horizontal.

For the test each fuse was pulled in and out of the holder 3 times and also wiggled/rotated while it was in it. The results are the average and/or most consistent reading.

All of the following are the 5x20mm barrel fuses, with a descriptor and ohm of the "fuse" portion.

• 1x1x8mm square: 1250 ohms
• 2x2x8mm square: 500 ohms
• 3x3x8mm square: 350 ohms
• 3x8mm hollow: 300 ohms
• 3mm perpendicular hole: 300 ohms

Obviously these are quite high for a fuse, but we are already down this rabbit hole so lets keep going.
