Parametric Precision Sealing Clip

This universal sealing clip is suitable for almost all soft materials such as film bags and balloons. The clamping force is distributed evenly to prevent damaging the material and seal across larger areas.

You can measure the thickness of the material with a pair of calipers and use that value for the gap. If your printer is well calibrated the value shouldn't need too much adjustment, if any at all.

It is designed not to have any sharp points but you may have to check the final print over
