Sewing Spool Holder Cap

thingiverse

This piece will securely hold a sewing machine spool in place while it's being used. The curved sides prevent snags, and the flexible center keeps everything steady. This model was specifically designed for a Brother sewing machine with a 5mm diameter. It can be adapted to fit any sewing machine by simply scaling up or down to match your desired spool pin size. To determine the right scale factor, measure the size of your spool pin and use this formula: Scale % = (Pin Size) x 20 For example, if you have a pin size of 6mm, calculate the scale factor by multiplying 6 x 20, which equals 120. This means you should scale the model up by 120%. I've created four different versions to accommodate various spool sizes: small, medium, large, and extra-large. My wife typically uses the "Large" size for most of her projects. Small = Diameter 20mm Medium = Diameter 30mm Large = Diameter 40mm Extra-Large = Diameter 60mm
