Peptide & Insulin Pen Storage Case with Latch

This compact yet fully functional storage case was designed from scratch to safely organize and transport your peptide or insulin therapy essentials. It prints all on a single bed and takes only about 5 hours to complete. The box features a locking latch and custom insertable hinges to accommodate the full size without needing oversized printers.

After many iterations, I dialed in the fit and function—this final version is dialed for practical daily use and is clean enough to toss in a drawer, gym bag, or medicine cabinet.

Two versions are included:

• One for large bacteriostatic water bottles

• One for standard smaller vials

Each case holds:

• 1 carpule
• 2 insulin pen needles
• 8 peptide vials
• 1 bottle of bacteriostatic water
• 1 reusable insulin/peptide injection pen
• No supports needed
• Print in PLA, PETG, or ABS for durability
• Designed to assemble easily after print
