This 3D-printed spacer washer is designed to solve a common mounting issue with the SmallRig Universal Quick Release Mount Plate Kit and similar Arca-style accessories: the included or standard 1/4"-20 screws are often too long, causing interference with camera cages, tripods, or mounting plates.

By placing this washer between the screw head and the mount, you can safely tighten everything down without stripping threads or damaging the aluminum hardware. The thickness is fully customizable—simply adjust the Z-height in your 3D slicer to get the exact clearance you need for your specific setup.

Key Features:
• Press-fit design for a secure, non-slip hold
• Easily adjustable thickness by scaling the Z-axis in your slicer
• Perfect for clearing excess 1/4"-20 screw length on the SmallRig 2144B and compatible Arca mounts
• Recommended for long-term use with durable filaments

Printing Tips:
• Modify the Z-height in PrusaSlicer, Cura, or your preferred slicer to match your exact screw and plate thickness.
• The inner diameter is sized for a standard 1/4"-20 screw
