This little clamp is to help maintain off contact for screen printing on manual single clamp style printing presses like Riley Hopkins, Vastex, etc.

Keep in mind this design isn't perfect but it's better than taping quarters to the bottom of your screens. Also, BE SURE NOT TO OVER TIGHTEN. Since this off contact is set at 1.75mm, the plastic is rather flexible with some materials.

NOTE: If you plan on using this in production with a flash dryer, you may want to print this in PETG or ABS to withstand the heat. Or just give it a try with PLA.

Happy printing :)
