FLEXICLIX Socket Holder for Miter-Track Rails

FLEXICLIX - Flexible socket holder system for Mita-Track 19/24 mm aluminum T-slot rails

---------------------------------------------------------------------------------------------------------------------

 Update 09.08.2026

1.  Added several variations of 1/4" (6,3 mm) hex-bit holder for the Mita Track rails 

2. Added a Miter-Track T-nut for 3/4" (19 mm) wrench socket, 36 mm wide

3. Added several shield clamps as wrench tool holder with different diameters for individual use on wood panels or other flat surfaces

My challenge was that I needed a flexible holding system where the sockets wouldn't rattle around loosely (in recesses) or fall out during transport in a tool case. Similar attachment systems are offered by various online vendors (BGS, HAZET, KS-Tools, NICROMI). Ultimately, however, none of them met my three main requirements: flexibility, clamping capability, and space.

I designed this FLEXICLIX system for the follwoing socket sizes to use in Mita-Track rails:

3/4" inch (19,05 mm)

1/2 inch (12,5 mm)

3/8 inch (10,0 mm)

1/4 inch (6,3 mm)

1/4" (6,3 mm) Hex-Bit holder 

Miter Track Profiles: These T-slot tracks (miter tracks or also miter slots) are commonly used for miter jigs and sliding sleds on workbenches, router tables, or table saws in woodworking and carpentry; they are also ideal for keeping tools—such as the 1/4", 3/8", and 1/2" sockets shown in this example—within easy reach.

The filament and printing parameters I used for these initial versions:

Filament: Tinmorry PETG-ECO
Nozzle Temperature: 240°C (initial layer) / 235°C (other layers)
Plate Temperature: 75°C (initial layer) / 70°C (other layer)
Nozzle: 0,4 mm
Layer heigt: 0,2 mm
Initial layer heigt: 0,2 mm
Line width: all settings on default 
Wall loops: 2
Top surface pattern: Concentric
Top surface density: 100%
Top shell layers: 2
Top shell thickness: 0,4 mm
Top paint penetration layers: 1
Bottom surface pattern: Concentric
Bottom surface density: 100%
Bottom shell layers: 2
Bottom shell thickness: 0,4 mm
Bottom paint penetration layers: 1
Internal solid infoill pattern: Rectilinear
Sparse infill density: 35%
Sparse infill pattern: Grid
Infill/Wall overlap: 15%
Speed outer wall: 100 mm/s
Speed inner wall: 100 mm/s
Speed Sparse infill: 100 mm/s
Speed internal solid fill: 100 mm/s
Speed Top surface: 80 mm/s
Support: no

A filament with elastic properties, such as PETG, is recommended for these flex-nut holders. Pay attention to the optimal printing temperature when doing so. If PETG is printed at an excessively high nozzle temperature, its chemical and physical properties change. 

Additional FLEXICLIX holders are being planned, such as for bits with 1/4" (6.3 mm) external hex drives.

Note:
Manufacturersof hex sockets may have varying tolerances; consequently, a socket from Manufacturer A might initially require more force to push onto the retaining springs than a socket from Manufacturer B. If the socket feels too tight on the retaining springs, you can use a fine file to remove 0.1 mm to 0.2 mm of material from the longitudinal surface of the springs on each side until the force required to attach and remove the socket feels comfortable.
