Can easily hold 28 guitar picks (2 per slot) if they're less than 1mm thick. There's enough spacing between slots to quickly and easily grab a pick if you drop one while playing.
v2 has perforated support pieces between the slots because I wasn't getting any bed adhesion. Download v1 if you don't want these support pieces.
Sometimes a pick will get wedged into the bottom inside corner and get a little stuck. This doesn't happen often but it's annoying when it does. Rounding out and/or tapering in the slots will probably help prevent this.
