Hi, this is my project.<p>Background: I bought my mum one of those customisable calendars for christmas where you can upload your own photos for each month. Since then I’ve been wondering how the on-demand printing industry works. My calendar was cheap, good quality, & delivered next day which I thought was very impressive.<p>I decided to do an experiment to see what I could learn. As a first step I’ve made some mug designs and I’m using zazzle.com for the manufacturing/purchase handling etc. This lets me see how their funnel works for product designers. I picked mugs because I wanted some for myself.<p>I needed a niche audience for my experiment and I chose HN readers. Mostly that was just because I am already familiar with the audience but using HN also gives me the benefit of being able to reach customers quickly and free of charge via a Show HN post.<p>Happy to try and answer any questions etc...
