Simple French Cleat holder for 150mm or 6 Inch Hook and Loop Sanding Paper.

Sized to easily hold an entire Pack (50) of 3M Cubitron, 

since I needed bulk storage and not those nice but small holders already available.

45° angle for 18mm or ¾ Inch cleats.

PLA works but I would recommend for PETG for strengh.

125mm / 5" Version available here:
