52mm x 35mm x 12mm bearing pillow

Made this to sit on top of a dehydrator tray and hold the bottom race of a 52mm x 35mm x 12mm thrust bearing (specifically [this one](https://www.amazon.ca/gp/product/B00E0ERR6W)). Includes little indents to make removing the race easier.

Made this to fit on top of a dehydrator tray (to hopefully eventually hold a spool holder).
