This is a heavy-duty replacement slider bracket designed to fit standard extruded aluminum T-slot tracks found on folding hard tonneau covers (Bison/BakFlip-style systems).

The part functions as an adjustable prop rod receiver carriage, allowing the prop rod to slide and lock at various positions within the vertical rail. It restores secure upright support when the tonneau is folded against the cab.

Designed for:

• Aluminum T-track extrusion systems used on hard folding tonneau covers

• Prop rod mounting applications

• Adjustable vertical positioning

Material Recommendations:

PETG (recommended minimum, set to 255 degrees celcius)

ASA (ideal for UV exposure)

ABS (acceptable with enclosure)

Nylon or CF-Nylon (maximum durability option)

Important:

This component is load-bearing and exposed to vibration, UV, and temperature swings. Print with high-strength settings and appropriate material for outdoor automotive use.

Recommended Strong Print Settings (Creality Slicer / Typical FDM)

Material

Preferred: PETG or ASA

Avoid PLA for long-term vehicle use due to heat creep and UV degradation.

Nozzle

0.6 mm nozzle strongly recommended for strength

(0.4 mm acceptable if settings below are followed)

Layer Height

0.24–0.28 mm (with 0.6 mm nozzle)

0.2 mm (with 0.4 mm nozzle)

Perimeters / Walls

Minimum 5 walls

Target wall thickness: 2.4–3.0 mm total

Top/Bottom Layers

8–10 top layers

8 bottom layers

Infill

60–80%

Pattern: Gyroid

Print Orientation

Print as oriented with a brim if adhesion is in question on your bed.

If maximum strength is required, print 90 degrees to normal so that load forces act across layer lines rather than separating them

and avoids shear load directly between layers. Youll need supports for the middle, but I've seen plenty of strength from PETG printed hot.
