Keycard holder

A tiny two-piece badge holder that snaps around any standard keycard and keeps it from falling out—no springs, no screws, just a hidden lip inside that grips the card. You print two halves which can be combined in multiple ways (takes about 15 minutes each on PLA or PETG), add some superglue on the edges, clamp them together, and you’re done.Hidden latch: A small internal ridge catches the card’s edge so it won’t slip out, even upside-down.Glue-together halves: Fast prints, low material. Superglue the two shells and you’ve got a rigid, one-piece holder.Faceplate options:Engrave or deboss your name, company, club logo, whatever.Or leave it blank for a minimal look.Mounting tabs:Top loop for zipper pulls or lanyards.Side tab for badge reels, clips or straps.You can mix-and-match mounts on any side—or even slap two on at once.How to use:Grab the STL files (holder halves + your choice of mount).Slice at 0.2 mm layers, ~15% infill.Print each part (~15 min).Drop superglue on the edges, press
