Compact Multi-Angle Spirit Level (0-45-90°)

Compact Multi-Angle Spirit Level (0-45-90°) with Side View Windows

Description: This is my first design! A compact, ergonomic, and highly functional spirit level housing. Designed with both precision and usability in mind, this tool is perfect for DIYers and Makers.
 

Key Features:
-3-in-1 Measurement: Includes dedicated slots for Horizontal (0°), Vertical (90°), and 45° angles.

-Dual-View Windows: The 0° and 90° slots feature integrated side-view windows. This allows you to check the bubble alignment from multiple angles, not just the front.
-Secure Retention System: Each slot includes an integrated retaining lip at the bottom to prevent the vials from falling through while keeping them perfectly seated.
-Snap-Fit Design: The internal geometry is optimized for a firm friction fit, meaning your vials will stay secure without any glue or extra hardware.
 

Technical Specifications:
-Body Dimensions: 82 x 52 x 18mm
-Vial Compatibility: Optimized for standard 40mm (L) x 15mm (W) x 15mm (H) rectangular vials.
-Slot Internal Dimensions: 42mm (L) x 15mm (W) x 16mm (H).
-The slight clearance ensures a perfect snap-fit for standard 3D printed tolerances.

Supports: 

Although I successfully printed this without supports, I recommend adding minimal  supports for the windows to ensure the cleanest possible finish across different printer setups.
