Solder Paste Printer

Those machines are usually made out of aluminum and are really expensive. So i designed one that can be 3d printed. I tested with a PCB i made that had a USB-C 16 pin connector. And i managed to get it right. So I guess it works!!

It can support PCBS up to 10x10mm and its adjustable.

I printed everything in PLA, but i guess printing it in ABS or PETG would suffice.


# Materials

8x M4 10mm screws (any)
10x M4 5mm allen flat head screws
7x M4 nut
3x M4 heat set
Some silicon pads

# Assembly guide

You'll get the 10mm screws and put them on the outer and middle holes of the left and right support (file named set-1.65mm.stl), put the as far as they go, maybe use some pliers or a a tool to screw them all the way in.

Then get the flat had and put in the two remaining holes.

Slide two nuts in each of the side holes, align the support holw with the nut and screw the allen screw on it.

Now screw 2 or 3 nuts in the middle hole and use the 5mm screw to put in place the vertical holders.
