+**Straight Needle Cylinder Models** 
+
+This folder contains STL files for straight needle cylinders exported from Onshape. Each model is labeled by diameter, length, and anatomical use. All designs follow standard threading and wall thickness constraints.

+ General Notes 
+
+- Minimum wall thickness: aim for 2 mm, will allow 1 mm  
+- Minimum distance between needle thread base centers: aim for 6 mm (absolute 5 mm)  
+- Minimum distance between needle thread base center and tandem thread base center: aim for 6 mm (absolute 5 mm)  
+- Needle channel diameter 2.7 mm (thread 3.2 mm, depth 3.5 mm)  
+- Radius of needle curve: 35 mm  
+- Tandem diameter 3.8 mm (thread 5.0, depth 7.0)  
+- Barrel length can be reduced to 2 mm, if needed to meet spacing constraints  
+- Maximize number of needles while meeting spacing and wall thickness criteria  
+
+---
+
+Priority of Constraints                
+
+1. Radius of Curvature  
+2. Needle Center to Needle Center  
+3. Tandem Center to Needle Center  
+4. Number of Needles (OK to add 1 more if WT ≥ 1.5 mm)  
+5. Wall Thickness  
+6. Barrel Length
