Peg Board Tool Holder

I made this thing to fit my metal pegboard rack that I recently purchased. Most of the pegboard holders that i see on Thingiverse waste plastic, so I wanted a minimalist design that was fast to print and conservative on plastic.

There are several variables that you can tweak.

All measurements in millimeter, but I'm in the USA so my sizes are relative to standard US pegboards.

// Tool Handle Diameter (in mm); max size is about 24 mm if doing multiple connected
tool_dia = 24;
// Thickness of the tool holder
shell_width = 2;
// Height of your tool holder (10mm is a good guess)
holder_height = 10;
// Peg Hole Size (6.5 is good for US)
peg_size = 6.5;
// Peg Length is the thickness of your peg board
peg_length = 2;
// Peg Spacing, US=25.4; Metric=25??
peg_spacing = 25.4;
// Number of holders
number_of_holders = 5;
// Arrangement, grid, inline, inline_connected
arrangement = "inline"; //[grid, inline]
// Grid rows, duplicates number_of_holders on multiple "rows"
