Cut your micro SIM cards down to nano size without the stress. This 3D-printed jig holds your SIM steady and shows you exactly where to trim so nothing goes wrong.
The template has numbered slots that guide you through each cut. Place your micro SIM in slot one with the contacts facing up, align it with the embossed rectangle, then trim away what sticks out. Move to the next slot and repeat. Flip the jig over and cut on a flat surface to keep your hands steady and your fingers safe from sharp blades.
Made from measurements of real SIM cards, this jig works with whatever cutting tool you have on hand. If your SIM breaks during use, let the creator know so they can make improvements. Just be careful and take your time when cutting.

What it is made of
Designs like this print well in PLA. Compare the materials.
Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
