Need a place to store your tool that has some modularity for expansion and customization? These modular blocks allow for the needed layout of tool storage with a simple snap fit similar to a non-descript building toy block :). 2 blocks and 2 end caps together con fit inside a generic silicone mat from a-z.

The silicon mat where 2 blocks fit can be purchased here https://www.amazon.com/Kaisi-Insulation-Silicone-Position-Soldering/dp/B07DGVRYL3

-=[ General instruction ]=- - Use supports, I used tree supports for the test prints - Print 2x of the CAP and at least 1 tool block - There is a space on the bottom of the end cap to use a flat tool and pry it off if needed.

Update Apr. 15, 2026 Added stl and step for a blank block for makers to create their own modular block
