Minimalist 3d-Printable A6 Photo Frame Design with Locking Support

We are seeking a skilled designer to create a minimalist, 3D-printable desktop photo frame. The primary objective is to design a sleek, ultra-thin frame specifically tailored for the standard A6 photo format (105 x 148 mm). A key functional requirement is the integration of a locking support mechanism to ensure stability and practical use. The final design must be optimized for 3D printing, considering material efficiency and ease of assembly.
Project Brief : MinimalistA6 Desktop Photo frame  With Retractable Stand
1. Project Overview
Dimension & Profile
Bezel & Thickness :
the frame must features the smallest possible borders and thickness to achieve a highly elegant, minimalist appearance.
Orientation :
Versatile design (ideally supporting both portrait and landscape orientation, if feasible within the mechanism).
Retractable Stand mechanism
Tilt Angle :
A retractable stand on the back must support the frame at a slight, ergonomic viewing  angle when placed on a desk.
Locking Mechanism :
The stand must include a secure locking system to prevent it from accidentally collapsing or closing while in use.
Flush Integration :
When folded/retracted, the stand  must sit perfectly flush within the framers rear structure. This ensures the entire assembly remains completely flat, ultra- thin, and highly portable.
Manufacturing & Materials
Production method: Optimization for 3D printing(FDM or resin)
Design Consideration :
The parts should be designed with 3D printing tolerance in mind, minimizing the need for complex supports and ensuring easy assembly.
2 . Deliverables Expected
3D CAD Models :
formats suitable for manufacturing and review.
3D Printable Files :
optimizing STL or 3MF files.
Exploded View / Assembly Guide :
Quick documentation showing how the components (frame, stand, locking mechanism, and photo-retaining method) fit together.
What 3D printing process or material do you target?
Frame Geometry & photo Retention
Outer Dimensions : 111 mm x 154 mm ( providing a razor-thin 3 mm bezel around the A6 photo.
Total Thickness : 5.0 mm (Frame body: 3.0 mm + Embedded stand depth: 2.0 mm)
Internal slot Architecture :
A1.2 mm deep of the frame allows an A6 photo and a 0.8 mm protective clear PETG/Acrylic sheet to slide in from the top or side.
Flush Retractable stand and Hinge Design
Pocket Integration : the back of the frame features a precise 2.0 mm deep recessed pocket that mirrors the outer silhouette of the stand. When closed, the stand sits perfectly flush with the back.
The hinge system: A print-n-place (PP) cylindrical hinge or a 0.8 mm steel pin insertion. For FDM printing, a horizontal teardrop-shaped pin with a channel with 0.25 mm clearance tolerance ensure the hinge rotates smoothly without fusing.
Safety locking Mechanism :
To prevent accidental collapsing, the stand utilizes a mechanical detent (Snap-lock) system embedded directly into the hinge geometry
The mechanism : A micro-ridge (bump) on the rotating knuckle of the stand snaps into a matching recess inside the frame housing when the stand reaches its optimal viewing angle.
