This is tool to set sewing needle to the bobbin timing on the sewing machine.

For tool usage look here: "youtu.be/ZoxxVepXr0k?t=1237" (video is not made by me - but I recommend this and other videos from "In Stitches" on YouTube).

Instructions:

• You will need M3 screw for "Cramp part" assembly.
• I would recommend Cramp v1 - strength it is more than enough.
• Print with "Extrusion Width" set manually to 0,5mm (even with on 0,4mm nozzle).
• Layer height 0,15mm but 0,2mm should be also OK.
• Cramp v2 is stronger but will need supports.
• Scale "Gauge part" in Z axis to get exact height you need (2.5mm in the design but not all printers are equal).

Please leave feedback and post your printed parts.
