It's just a 3D model saved in the correct format.Where did you come up with the "plan" (not sure what to call it) for the 3D printer?

3D printed some terminal covers.
I would say fairly easy to learn. I have been around engineering all of my career but have never done mechanical design. There is a lot of help on the internet. I have a $200 printer and a free design program. I just start trying to make something and keep after it until it works. A set of calipers is most helpful.really like those covers, nice work. This 3d design and printing is really impressive. How hard is it to learn for someone with basic computer (but no engineering) skills?
I was searching around and found fire resistant 3d printing materials but I have no idea how much it costs or if it is hard to work with.No plans. Just measured them and drew up what I wanted. They are intended to prevent fire more than they are meant to supress or survive fire. It is PLA material (should burn well).
I would not have expected such material for a typical low end 3D printer to exist.....heat and extrude type. Wow.I was searching around and found fire resistant 3d printing materials but I have no idea how much it costs or if it is hard to work with.
I've been thinking about buying a 3D printer specifically for making terminal covers. I will probably find other things to do with it.
It probably still will melt just the sameI would not have expected such material for a typical low end 3D printer to exist.....heat and extrude type. Wow.
I am trying to stick to materials that won't feed the fireIt probably still will melt just the same
Just won't catch fire from external source (sparking wire)
Normal plastics will.
edit: These batteries are going to sit around for 10 years.Eventually.. everything burns..even cement base...
Let's hope it never comes to that!!
I will have most likely the same approach of @Hedges, in my case cut a few parts of garden hose to cover the bare bars, just to prevent accidental short if something would fall in between.
The ultimate goal is to keep the roof from catching on fire. Hopefully we can each come up with a solution that does that.In case of fire I now have Halon tank that will put it out at 68c temp.
I wouldn't worry too much about a buss bar covering thermally insulating the terminal Heat is harder to insulate. It takes sealing and thicker material.@ArthurEld , that's what I was worried about also.
It is the "heatsink" of the batteries.
Perhaps no garden hose...
What doesn't conduct electricity but does conduct heat??
Where did you get Halon? I thought it was worldwide banned? CO2 tanks are plentiful and cheap.It probably still will melt just the same

Silicone is a great idea. Fiberglass would work.I wouldn't worry too much about a buss bar covering thermally insulating the terminal Heat is harder to insulate. It takes sealing and thicker material.
I'm always into making things out of Obtainium. Anything household that could work? Silicone baking sheets? I like the car hose. Fiberglass from scrap parts?
Looking at the specs it is using HCFC instead now.. and didn't want to change their brand name? http://halotron.com/technical_info.phpWhere did you get Halon? I thought it was worldwide banned? CO2 tanks are plentiful and cheap.
I need to correct: Halotron.Where did you get Halon? I thought it was worldwide banned? CO2 tanks are plentiful and cheap.
Since the powder coatings are preferably applied using electrostatic spraying equipment, sufficient electrical conductivity of the surface is a major requirement and the correct moisture content plays an important role as well. To this end, a new sophisticated procedure was developed to measure the electrical resistance (surface and core resistance) during pre-heating. The results show, that the electrical resistance of MDF is influenced by board temperature and moisture content. Moreover, it is confirmed that pre-heating proves to be an efficient method to improve the powder application onto non-conventional substrates.
The type X would be a heavy lidSilicone is a great idea. Fiberglass would work.
But I was thinking a piece of Type X drywall would be cheap and easy.
Either just lay it on top or make the compression fixture higher to hold it up.

I was planning to cut it to the size of my battery so that helps some.The type X would be a heavy lid
