17/02/26 UPDATE: Uploaded a v2 - I added extra reinforced support on outer edges. Due to the immense winds we had recently, I add had to replace the previous model. Note that there is about a 5-8mm difference in hole's position.
I also increased the back with about 1mm

Sliding Gate Guide Bracket – Print-in-Place Roller Support

A tough, print-in-place bracket designed to guide and stabilize a 5 cm-wide automatic sliding gate. The integrated rollers keep the gate aligned during movement and reduce wobble, making the whole opening/closing action smoother and quieter.

Print Specs

Layer height: 0.2 mm

Infill: 25% -30%
Wall Loop: 4

Material: PETG (recommended for outdoor durability, heat resistance, and UV exposure)

Supports: Minimal – only under the roller hinge area

Print-in-place: Yes, rollers free after a light wiggle

Features

Fits standard 50 mm gate frames

Built-in rollers for smooth lateral guidance

Strong walls + outdoor-ready geometry

Mounting holes included for easy installation

Designed for real-world wear, weather, and daily gate cycling

Notes

Give the rollers a gentle twist after printing to release the print-in-place mechanism.

Feel free to remix or adapt to your gate hardware—tag your makes so I can see what setup you’re running.
