Heater?
#1
I need to work in a cold garage. Is anyone using a heated box to run their printer in?

There is this https://www.thingiverse.com/thing:3833875 and he has a mini heater; you really got to be careful with heaters this close. I really don't recommend putting a heater in there.

I would say a better way is to make an enclosure similar to what you use for FDM printers and add a temp controlled heater and install a smoke alarm just incase.

Alternatively you could try printing the case above remove the heater section, add a second vent opening and setup a heated air flow and fan ventilation system in one. By allowing you heat in, vent out, and full air cycle in one go you can have a controlled printing temperature every time regardless of the outside temp and you'll not have to worry about the chemicals in the air. (With an air filter, you could setup a loop back with an exhaust.) Idea

Just my two cents. I can send you the design.

Hi, i have the same Problem,
so i built a woodenbox and put a 800W heater in it, whitch is controlled by an thermostate for Floorheaters.
It works fine. In my garage the temparature around 11°C at the moment and in my box warmely 22 - 28°C Wink

I just got my mars after I had my previous resin printer stolen, and from experience I knew I needed to heat it.

Luckily I went for a simple - if somewhat inelegant solution.

I used a 12V, 150W Constant Temperature PTC Electric Fan Heater connected to a W2809 W1209WK DC12V Digital LED Thermostat Temperature Controller Module powered by an old PC PSU I had laying around.

I simply made a hole in the top of the acrylic cover for the wires in the rear corner, then stuck the heater to the same corner about half way down using strong double sided tape, I will change that to epoxy now that I have tested it working and the temperature probe near the bottom.

I then attached the thermostat display/control on top of the cover and wired it to power using a PCI Express GPU power extension cable so I can disconnect it easliy from the PSU.

Seems to be running nicely, although if I did it again would go for a 100W heater as at the moment I have to set my desired temperature a couple of degrees below what I actually want as although it cuts power at 25 degrees it takes a while for the heater to cool down and the temp tends to overshoot by a 2 degrees before it cools Smile

Does the job and as I already had a PSU it all came to under £20 to do (I used amazon prime so over paid for the parts).  If you need a PSU a 12V LED PSU is cheap enough and probably a neater option.  I will probably upgrade to one of those once everything settles back down in the world.
