Bubble String Level

Used in gardens to level ground, hangs on string. 

This is made for bubbles I had in my drawer, and I do not know where I got them… Their diameter is:
 

• diameter: 8mm
• lenght: 35mm

Its fair press fit, and should not disassemble on its own, but you can add some hot glue on ends ( there is a space for it ). Holders are indexed so they fit one way together.
