Included Mount Types (via Print Profiles)

Screw Mount (Parametric + Preconfigured)

The included OpenSCAD script supports a wide range of flat head screws, including:

• Metric: M2–M8
• Imperial: #4–#12, 1/4”, 5/16”

Several preconfigured print profiles are included for commonly used sizes:

• M3, M4, M5
• #6, #8, ¼”

You can also customize:

• Screw size and head type (flat, pan, round)
• Hole spacing and offset

• Plate size, orientation, and countersinking

  All via the Screw_Specification and other parameters in the .scad file.

Multiconnect Mount

• Provided in both Multiboard and OpenGrid spacing
• Includes vertical and horizontal orientations
• Compatible with the standard Multiconnect ecosystem

GOEWS Mount

• Compatible with GOEWS cleat-style rail systems
• Includes vertical and horizontal orientations
• I recommend using flush bolts for GOEWS

Multipoint Mount (Multiboard Snap-In)

• Snaps directly into Multiboard backers
• Provided in both vertical and horizontal orientations

Printing Recommendations

• Most mounts can be printed flat on the bed with no supports
• Mounts with overhangs (e.g., GOEWS) should be printed on their side with tree supports
• Use 15% infill minimum and 3+ perimeters for strength
• Screw mounts are designed for flat head screws to sit flush in countersunk holes (UniFi typically includes M3 screws)
• Be careful when removing mounts from the bed to avoid flexing or cracking
