Penny Flinger
thingiverse
Just whipped up this little penny launcher because it was there. Prints in two pieces that fit together neatly. It's printed quality shouldn't make a difference, I built it with some wiggle room for tolerances.\nUpdate: Just gave this a try and it launches pennies pretty well, though the handle is a hassle so I made a finger-held version which is currently printing and will upload instructions along with a video later showing how to use it.\n\nInstructions\nTo get started just print it in medium quality. Snap it together after cleanup, pop in a penny, and give it a little nudge!\nModels are designed to support easy removal for 0.35 nozzles using minimal material. This approach has worked so far for me with models without any issues.\nUpdate: Just stick your index finger through the hole, then grab onto the tab with your middle finger. A quick flick will launch your penny in style!
