Hydrometer Holders

Description:

I encountered a problem after purchasing a vacuum sealing kit for the filament spools of colors that I rarely used – my hydrometers kept having their air inlet vents covered (and sealed) by the vacuum sealed pouch.

I made this to create an open space to allow air to flow freely into the sample vents on my hydrometers.

Update: I have since made two more versions. The first is a square variation of the round hydrometer holder that can be placed in a locations other than the filament spool hole. The second is a variation that holds rectangular hydrometers as I could buy 12 rectangular hydrometers for the same price as two round ones.

Printed with the Following Settings:

PLA 0.2mm layers 15% infill tree supports brim adhesion
