This OpenSCAD script generates a customizable two-part hose clamp block designed for precision fit and easy assembly. It’s ideal for securing tubing, conduit, or cylindrical components in 3D-printed enclosures, robotics, and DIY builds.

🔧 Features: 

• Parametric support for multiple hose diameters (e.g. 3/16", 1/4", 3/8") 
• Automatic spacing and bolt clearance logic
• M6 bolt hole with optional socket head recess 
• Rounded top and vertical edges for strength and printability 
• Snap-fit alignment tabs on the top clamp with matching recesses on the bottom clamp 

📐 Geometry: 

• Tabs are flush with the left and right ends of the top clamp 
• Recesses mirror into the bottom clamp for perfect alignment 
• Bolt hole is centered between the most central hose pair 

🛠 Key Parameters: 

• line_diams: List of hose diameters in mm 
• slot_clearance: Extra clearance around each hose 
• slot_spacing_input: Minimum spacing between hoses 
• margin_x/y/z: Padding around the clamp 
• fillet_r: Radius for rounded corners 
• bolt_d, recess_d, recess_depth: Bolt and socket head dimensions 

🧪 Fit Tuning: 

• Tab dimensions and clearance are adjustable in alignment_tabs() and alignment_recesses() 
• Default clearance is 0.3 mm for a snug, printable fit 

🖨 Output: 

• Uncomment one or both render lines at the bottom to preview or export each clamp half 
• Designed for FDM printing with minimal support
