+# Contact Printer Snoot
+
+![Contact printer snoot with a 1mm opening](./img/contact_printer_1mm_slit.jpg)
+
+The contact printer snoot is designed to fit on the end of a small flashlight and be used to print negative onto print stock using a synchronizer block.
+
+This was published with support from the [REMI](https://re-mi.mire-exp.org/wiki/doku.php?id=start) project.
