Connecting Rod Bottle opener split pattern for sand casting

thingiverse

I crafted this sand-cast connecting rod bottle opener with precision. This part features a split mold design for sand casting, boasting a minimum of 5 degrees of draft on all surfaces to facilitate effortless removal from sand molds. To assemble it correctly, print two identical parts and join them using 2.5x6mm pins in the far holes. I made adjustments to enhance functionality by narrowing the gap between the opening blades to 15mm. In contrast, the original pattern and castings had a wider 20mm gap, which often resulted in a poor grip on the glass lip of the bottle, causing frustration.
