I bought my wife a robot vacuum for Christmas, it's what she wanted, and then
I 3d printed a part to make it work better I'll explain it all on today's
Filament Friday. Filament Friday is brought to you every week by the
generous donations of my patreon supporters. Here's the problem I have
with this vacuum it was low enough to go underneath some of our furniture like my
favorite chair but in the Middle where it sags a little bit the robot would get
stuck and then just shut itself down so I would then have to go yank this thing
out and reset it and it also did this underneath our couch it was just low
enough to get into the couch and then stick itself and shut it down again we
had it run at night one time when we walked up to it stuck just like this. I
flipped it over and I could see a switch on the inside of the front bumper when
this switch is pressed it reverses direction this is the same type of
switch that's used on 3d printers as an end stop so there was a gap there and
then on top there was a gap and once I pressed the bumper and I could hear the
switch click I still had a gap so I thought maybe I can make a bracket that
will stick up in the air and snap into this groove so that's what I tried to
make I went to Tinkercad and this is a very easy design I just used a bunch of
block elements one that's tall at 120 millimeters another and a 90 degree
angle at 22, one lower at 14 millimeters and then two little blocks on the end of
those to make it into a snap and this whole bracket is 20 millimeters tall or
wide so I grouped all that together hoping I got my dimensions right so this
thing would snap in place for this project I'm gonna use the new Proto-Pasta
metal flake candy apple red I call it the CHEP candy apple red you know why
because I'm the one that suggested it to them and they actually listened in fact
they had me test some samples early on so Thank You proto pasta for listening
and giving us metal flake candy apple red filament I love it
exported the file from Tinkercad and brought it into my favorite slicer
simplify3d this is a very simple design I decided to print it on my Any
cubic mega i3 at a 50% fill point three layer height here's the temperatures
that I use for the HTPLA at a 60 millimeters per second so this shouldn't
take very long to print and after I sliced it it looked good and it said 42
minutes to print this thing so this should be a very quick fix and here it
is on the Anycubic it popped off fairly easily and this candy-apple red just it
glistens the camera cannot capture how good this looks so now it was time to
snap it on to the robot so remember that gap on the bottom where that switch was
it fits in there and then snaps over the front onto that lip and it looks like
it's got plenty of travel I can hear the switch clicking so hopefully this is
gonna work so now I need to test it on the carpet I can't believe this thing
worked the first time it hit the bumper on the couch and then it hit the 3d
print and then it went on another angle and it kind of got itself stuck but it
kept hitting the 3d print and reversed direction which allowed it to get itself
free and then move on to the rest of the carpet so that worked out perfect it
never got itself stuck now my chair it went in straight hit the 3d print and
reversed direction it's exactly what I wanted to do clean up to the chair but
not go underneath it so I'm really happy with it now I couldn't make it too tall
because I have a charging station that's underneath this little table so I was
worried that I might have made it too tall but it worked perfectly I'm really
happy with the way this worked out the only improvements I may make is a little
bit tighter and then maybe stretch this out with two more prongs coming up but
still snap in the same spot that way they get hit at different angles and
still push the switch so if you like useful 3d print projects like this maybe
