This is a redesigned version of the original model by @CharlesTimko, modified to accommodate 2 rails. The design is specifically optimized for a smaller 4x4 gridfinity base setup.

Print Settings:
- Layer Height: 0.2mm
- Infill: 15-20%
- Supports: No
- Material: PLA/PETG
- Perimeters: 3-4
- Build Plate Adhesion: Skirt/Brim

Assembly Instructions:
1. Print all components as oriented in the STL files
2. Clean up any stringing or support marks if present
3. Test fit the rails into their designated slots
4. Insert the 4x4 gridfinity base into the holder
5. Ensure smooth rail movement and proper alignment

Note: It takes quite some force to get these one. One tip is to align one leg with the rail and then push it over the other edge. 

Design Features:
- Dual rail support system
- Compatible with standard 4x4 gridfinity bases
- Improved stability with dual-rail design
- Space-efficient footprint
- No support material needed for printing

Notes:
- Original design credit to @CharlesTimko
- This is a modified version optimized for dual rails
- Suitable for desktop organization and workshop storage
- Compatible with standard gridfinity measurements
