When buying your first band saw, it is a good idea to buy a set of blades as well. Putting the bands with their sharp teeth in a drawer can easily become confusing. So I decided to hang mine over the room's door. These are 2630mm long and up to 20mm wide. I planned for two 4mm countersunk wood screws to hold this in place, but one per piece was plenty stable. Overall I put put too much thought into stability: this carries very little weight. I like to overbuild workshop equippment, though.
Of course, with a band saw, you can easily make holders from wood. I still preferred to print mine. These are made from PET-G but PLA should word just as well. I opted for .3mm layers which is not pretty but fast and stable. I also opted for a high temperature for reasons of stability. This needed to be printed diagonally on my printer bed (210mm edge length) to fit into my Anycubic i3 Mega,.
I did provide a commented OpenSCAD file which can be easily adapted for individual needs (wider or smaller blades, longer or shorter mounts, different screws...).
DAS FILAMENT PET-G
not too much, prefer stronger walls
It is intentionally a bit big for many base plates but apart from that a very uncomplicated print. Print it laying flat, so the layers are horizontally and prefer layer adhesion over a bit of stringing (so temperature rather "up").
Screw holes are small and slope is 45°, so don't bother with supports.
I have not tried it, but this should word with any material.
