Glue Spreader for Glass Bed

My preference for print surface is a glass bed and I use PVA wood glue diluted with 50% water when a bit extra adhesion is required. I was getting sick of spreading the glue with my fingers; - it doesn't produce a nice even coat, and I got sick of sticky fingers.

So I decided to print something that I can use to spread the glue onto the bed easily and evenly. My 'Glue Spreader' is a very simple design that took about 5 minutes to create in Fusion 360. It works really well. A blob of glue on the bed, and a twist and swipe leaves a nice even and smooth layer of glue.
