So while my kickstarter was ticking over I had a fair amount of time to complete some other large projects. This one involved me making 35 sets of rotating cake rings, where a set includes one big ring and one small ring. These rings are going into Harry Potter cakes as per the video in the link.
The trouble with ordering parts from China like this is that half of them were different. Many of the larger rings came with 3 mounting holes instead of 4 and none of the holes were drilled all the way through so I was unable to bolt them in place. I ended up drilling through the rings myself which was dull and time consuming.
