Singer Sewing Machine Power Plug

thingiverse

A Singer sewing machine power plug, which was used on machines from 1930's till mid 1960's. It can be found on many different Singer models, I tested on my 3x 401G's and 2x 431G's. Disclaimer: Be sure you know what you are doing, if you are not comfortable with electricity wiring, please ask a professional to do it. If you damage your machine, or even worse you get electrified, I won't take any responsibility. It is an easy and small print, print with ABS or PETG, it is possible to print with PLA, but I am not sure how long it will last, because of shape change with warmth. Please make sure to test the print before wiring, it should fit really tight, if it is too loose, print it a little bigger by changing the settings in your slicer software. Wiring it is not easy, there is not much space, so take your time while doing it, I also change design, so it should fit easier, STL files are little different than the pictures I uploaded. I also added another plug with only 2 female pins for some US models, these 2 pin versions only need power and the foot controller is connected trough another pug. I am not sure if this 2 pin model fit those plugs, since I don't have one, if someone test this out please report back, I would really appreciate it. Since the male pins on the machine are 4 mm and most stack up plug test leads are also 4 mm, I grabbed 3 female test lead connectors I already had lying around. These needs to be shortened, see the pictures for more information. I forgot to take pictures of the screws, but I used 3 mm wide and 20 mm long screws, any 3 mm screw will work, just make sure it is not longer than 20 mm. This model test lead female plugs are widely available, and should easily handle the current drawn by the machine, which is around 400mA on most machines here in EU.
