It started with my bathroom renovation. Two pipes hung crooked, and zip ties yellowed and cracked. Then I found a spool of PETG filament. Tough, flexible, waterproof. I designed a double clip in CAD, printed it — perfect fit! My plumber neighbor said: "Sell these!" Turns out, everyone has this problem. That's how these clips were born. No marketing brief, just turning pipe chaos into straight lines. From frustration to solution.
