Folder Trimmer 🗂️✨ A simple script to clean up unnecessary files from your projects (currently only for KiCad projects)
Heart is an open-source printed circuit board by AlexLymbo, from the AlexLymbo/Folder-Trimmer repository on GitHub. It is a 2-layer board of 36.5 × 28.5 mm with 13 parts on 10 nets, routed with 26 tracks and 2 vias.
It is built around the NE555D and BD136. Its parts include 4 resistors, 4 diodes, 2 capacitors, 1 IC and 1 transistor.
Folder Trimmer is a tool designed to help clean up unnecessary files from folders, specifically targeting KiCad files for now. Useful for saving space from autogenerated clutter and preparing projects for distribution.
Trimming KiCad Files: The script removes specific unwanted files from a KiCad project folder based on predefined patterns. Copying Files: It copies files from the target folder to a new folder called "trim," excluding files that match the trim patterns.
git clone https://github.com/yourusername/folder-trimmer.git
cd folder-trimmerpython folder_trimmer.pyYou will be prompted to enter the path to the target folder. The script will then process this folder, copying files to a "trim" folder and removing any files that match the trim patterns.

It measures 36.5 × 28.5 mm and has 2 copper layers, 1.6 mm thick.
13 parts, built around the NE555D and BD136. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the AlexLymbo/Folder-Trimmer repository on GitHub, at the commit this page was made from: the board is test-trim/heart.kicad_pcb and its schematic test-trim/heart.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask AlexLymbo before reusing the design.
