Coin cell battery holder that can be used in wearable electronics

thingiverse

I needed a budget-friendly way to utilize coin batteries in our wearables workshop with kids. After downloading several designs, I opted for KISS (Keep It Stupidly Simple). So I created a new one in Tinkercad, focusing on making something basic like a button! The initial design was a straightforward holder that featured holes for sewing conductive thread and establishing connections. Following the workshops, we revamped it to incorporate several enhancements: bigger holes for the needle (expanding from 2mm to 3mm), a notch for effortless battery extraction with any pointed object, and duplicated + holes so the button's orientation during sewing doesn't matter. Print Settings Printer: BQ Witbox Rafts: No Supports: No Resolution: 0.2 mm (first layer) / 0.3 mm Infill: 15% linear Notes: I'm using only one perimeter to ensure infill pattern inside and a faster print time. I rely on Slic3r as my post-processing software.
