Square jar emptying tool

In the UK lots of jams, chutneys, etc are sold in short square glass jars. Unfortunately this means that quite a lot of product gets wasted as a knife or spoon cannot reach into the top corners of the jar. This makes my wife angry.

So, I thought design a little tool to scrape around those corners. It is very basic but works quite well.

I printed it in PETG (food safe). But if you make one, remember to was it in the sink in hand temperature water - not the dishwasher!
