Loose discs rattle around tool bags and truck beds, chip against everything they meet, and end up in the trash. DISC GUARD is a twist-lock case built to ride in a work truck — so your discs show up in the same shape you packed them.

Thick-walled body, tight twist-lock lid, and a center post that keeps the stack from sliding. We put a prototype under a full-size pickup — drove over it, parked a wheel on it, drove off. It kept its shape. That's the standard every unit is printed to.
I spent years in a shop with a grinder in my hand. Every mechanic and every hand on a framing crew knows the ritual: reach into the bag, pull out a disc, find a chip in the edge, toss it, and cut with whatever's left.
"I got tired of throwing away discs that died in the bag instead of on the steel. So I designed the case I always wished someone sold — and printed it myself."
Every case is designed, printed, inspected, and packed by me, one at a time. Batch #1 is small on purpose — you're getting the first run.

Quarter-turn and it's sealed. No latches to snap off, no lid popping open in the gang box.
Fits 4½″ cutting, grinding, and flap discs on a center post that stops them grinding against each other.
Rigid PETG shell that takes drops, stacking, and road vibration — proven under an actual pickup.
Each case is printed and packed by hand. When these 8 are gone, the next batch ships in about 10 days. Orders ship within 2 business days via USPS.
