Dao cắt chỉ cho máy may (Thread cutter for Sewing Machines)

Do your scissors always disappear when you have finished sewing and need to cut the threads? 

Then this little handy tool is for you. 

Mounted with double-sided 3M tape and you are good to go with your sewing projects.

Stuff you need for great success:

• 9mm utility knife blade/box-cutter blade (the small ones)
• 20x50mm Double-sided 3M tape or equivalent 
• 3x10mm machine screw
• 3mm hex nut
  • (You can also glue the pieces together, the blades will last for years.)

The why:

• I created this for convenience to make my workflow faster. 
• Loosen my grip to pick up a scissor, and cut a few threads. 
• Then putting away my scissor to grip my fabric again is done many times during a sewing project.
• But no more hassle, I have a thread-cutter on all my sewing machines now. 
• I even have one extra right under my table for extra extra convenience 

The Printing:

• No support is needed for printing. 
• Do whatever you feel, all mine is done in PLA with 4 perimeters.
• print with the inside of the model up. The orienting is corrected in each model. (except for the STEP files, they are a mess) 

Post-processing: 

• The support structure needs to be cut away in the small cracks on all 4 sides so that the thread can run freely along the edge of the blade.

• I recommend using a screw and hex nut for long-lasting (or you can use glue). 
• I've pressed the 3 pieces together, used a screw with a hex nut to fixate the blades inside, and then double-sides 3M tape. I think it will be quite enough for a long time. 

Modify:

• I've included the STEP files if you wish to make the model differently. 

The end:

I have spent an awful lot of time on the small details to get it just right. I went through many iterations to present the best model of my ability. So I hope you like the sewing machine cutter and give it all the love that it deserves.

And please upload your make and leave a comment on what you think of the model and use. 

Happy printing and sewing.
