Multi-purpose keychain with screwdriver and rule

This practical keychain is an essential accessory for those who love to be always prepared. It transforms into a screwdriver when needed. Inside, you can insert two interchangeable tips: one flat and one cross, each 25 mm long, perfect for handling any small repair. Additionally, on the outside, there is a ruler with measurements in both centimeters (10 cm) and inches (3.937"), ideal for taking quick and precise measurements. Compact and functional, it is the perfect accessory for those seeking practicality and versatility in a single tool. I recommend setting 3 layers for the walls and 100% infill to prevent breakage during use.Happy printing and good work!Boost MeHelp me keep creating!
