A snap fit lid for Red Solo Cups with a coin slot / hole for use as a donation jar or raffle ticket box.
I needed a couple hundred simple, easy to print reusable raffle boxes for a dog rescue penny auction fundraiser. Found the original listed below, reduced the diameter and added the opening.
The author remixed this model.
Added the slot opening and resized the model to securely snap on to the red Solo cups I have on hand
