12g CO2 Capsule rack 7x7

thingiverse

This is a compact 7x7 printing grid that can be oriented upside-down, eliminating the need for supports during the printing process. It's not the most robust design and may not hold up well when moved around, but if you're looking to create a basic rack with minimal filament usage, this option might suit your needs. Built to fit snugly together, this grid is specifically suited for use on a CR10 printer, where it can be printed using PETG.
