on today's maker mashup we're building an emergency stop module so on today's makers mashup
we're going to be building one of these emergency stop modules now i had a terrible time i
looked on amazon i looked on the web and i was not able to really find a module where you could take
ac power on one side and have ac power on the other side with the emergency stop button in the
middle now maybe that's by design but i wanted to put something together where i it was a 3d printed
i could use this for anything so if i want to use it for the laser while i'm running that or
a 3d printer and one of the nice things about this is that if i want to put this with some
of the 3d printers that i do reviews on i don't have to alter the printer or anything else i just
put this together the print will take longer than the actual assembly uh the print takes about five
or six hours depending on your printer but it's a really simple print it's a really simple project
and it adds safety because this thing will support up to 10 amps so i can use this for
power tools in the shop i can use it for the 3d printer anything that you want to be able to stop
in an emergency and not have to fumble around finding the reset button which is what you find on
even the l301 or the x301 or a lot of 3d printers they have a reset button and a lot of
times that's used but i've run into times where i'm trying to fumble for that in an emergency
and something like this would be a lot better and it's very inexpensive to put this together it
was really about 20 in parts and then just the 3d printed parts and i had some screws laying around
so it was really simple to get put together so we're going to be building this today
and then we'll have the ability to have an emergency stop button for just about anything
here in the shop so with all that said let's get to work we start by 3d printing the enclosure and
we're going to do this with the face down you'll need some basic supports in order to bridge the
gap between the openings but i did this with some custom supports that you see here in cara
next we need to disassemble the stop button and surprisingly there's no instructions that i could
find for how to do this so eventually through trial and error i found that you need to remove
these outside screws first now once you remove these the two switches which are normally closed
are going to come off the bottom of the switch once you have the switches removed you're going
to insert a screwdriver in here and then this will allow you to pry it off the button itself this
snaps back into place later on but it is a little difficult to pull off the first time around once
you have that piece off then you'll just unscrew the retaining ring and we're ready to start our
assembly now we're going to insert the power inlet into our 3d printed enclosure and i bought
a pre-wired inlet which made this super simple and i have a link for this down in the description
to secure this to the enclosure i just used an m3 screw and a nut on the other side now i did drill
a hole to secure this to the enclosure and the reason why i didn't put the hole in the part to
begin with was because many of these are press fit but i only had the screw in type available
so this is the kind that i used and i figured it was easy to break out the drill now we need to
wire up the outlet and i created a small wire and this is for the hot line it's very crucial that
you interrupt the hotline and not one of the other lines because then this outlet could theoretically
be grounded so always make sure you're interrupting your hotline and not the neutral line
once we have the jumper wire installed we're going to flip this over and then install our neutral
wire and that's coming directly from the power inlet once we have our hot neutral installed we're
going to attach the ground line and screw that on as well this will keep everything safe because
we'll have a nice solid ground running directly from the inlet itself now once we've got this all
wired up then we're just going to secure it into the enclosure with some m3 8 millimeter screws
now we're ready to reassemble the emergency stop button you'll insert it into the face of the 3d
print and then use the retaining ring to secure it to the 3d printed part make sure you adjust
the ring orientation so the letters are in the direction you want before tightening everything up
underneath next we'll need to reattach the switch mount this just presses right on the back of the
button if you line it up and just use two thumbs it presses right back on no screwdriver necessary
using the switch from the right side we're going to insert the hot line from the outlet and we'll
tighten this down and then we'll repeat the process for the inlet on the other side now that
we have everything all wired up we'll screw these back onto the back of the emergency stop button
make sure your wiring is all tucked inside and then you'll screw the bottom plate on with some
m3 8 millimeter screws to test everything out i hooked up a small rotary tool and turned it on
and then you can see when i press the button the power is cut and the tool stops
so as you can see this is a really simple project to put together
3d printed parts of course is going to be the longest part of this project assembling it took
roughly 15 minutes but what i like about that is i can make a number of these and i can go ahead
and put them on 3d printers any power tool so even if i wanted to have something like
this on my drill press i can put this in here as long as it's less than 10 amps of draw power
this should work fine and you shouldn't have any issues with it and all of the wires will support
110 volts in the us so you may have to change your wiring if you're european but overall this is a
really simple project to make and i definitely recommend this if you don't have one for some
of your tools so with that it's going to bring the end of today's video if you enjoyed it make
