drawer \ slide \ coin holder for secrid card protector

thingiverse

After getting my hands on a Secrid card holder, all I needed was a spot to stash my house key and some cash so I could finally ditch my wallet. So, I decided to build this compartment that fits snugly at the bottom of the card protector. Note that it doesn't really slide out smoothly, which makes using it a bit tricky... To keep it in place, I used a hair band to attach it to the protector, and now it feels nice and secure – like nothing's going anywhere! The storage area is a respectable 5mm high. The FreeCAD design file is included for anyone who wants to give it a try. Later on, I stumbled upon another drawer (design #2212136) that looks pretty cool too!
