I recently took a class at my Community College hosted by my local Makerspace. The intro to cad class we used TinkerCad to create a shopping cart key. In my area we need a $1 coin aka a Loonie to rent a shopping cart while shopping.

beforehand Ive been 3d printing and selling items and the two main items sold are shopping cart keys because everyone uses card not cash (Walmart is self checkout) and can and bottle openers for the elderly

so I give you the Kart Wedge what I've Named “Wedggy Finger Multi-Tool” (to avoid the term Wedgie)

This Multi-Tool is good for prying things off delicate surfaces such as tables or print beds. good for scratching scratch tickets. unlocks $1 shopping karts. opens pop or soda cans. or just a spare finger, REMEMBER, Don't put your finger anywhere you wouldn't put your pecker… use a different tool even though people generally have 10 fingers and toes, use a tool

also with .4mm nozzle i was able to get good detail at .16 layer height and walls at 0.17 for commercial customization
