This is a model to replace the back plate, electronics cover on a Guild Pilot Bass. Fits 4 and 5 string. The originals are fragile and often break.
I've included a PDF vector file of the outline and hole positions for anyone who wants to make their own model.
The original part was .1 inch thick, you might want to print a bit thicker for strength.
I've added a version with no holes as I'm finding they didn't always put them in the same place.
The author marked this model as their own original creation.
