Triangular Pencil Grip: Mold for Silicone Casting

thingiverse

Make a 3D Printed 3-part mold for silicone casting projects using a Smooth-On brand Ecoflex product, which is a 2-part mix that cures over 4 hours after being combined and mixed. (https://www.smooth-on.com/product-line/ecoflex/) Wrap rubber bands around the channels to keep sections tight during the curing phase. Use a toaster oven for a quick, 10-minute cure at low heat (read more details at the Smooth-On website). The PLA print was porous enough to let the low viscosity liquid silicone seep through gaps. It's crucial not to let it ooze out over 4 hours! Make sure not to cure in an oven that you would also cook food in later. Designate this oven as your new "science oven".
