Mason Jar Honeycomb Paintbrush Holder Insert

This simple insert converts a standard mason jar into a stable paintbrush holder. The honeycomb grid keeps brushes separated so the bristles don’t bend or deform, and the insert holds them upright for drying or storage.

I designed this for my miniature painting workstation so brushes can sit neatly inside a stable mason jar while still being easy to grab. The lower fins center the insert inside the jar and keep the brushes more or less vertical.

Features:

• Fits standard mason jars

• Honeycomb grid organizes brushes individually

• Centering fins keep the insert stable in the jar and the brushes upright

• Prints easily with no supports
