@larry4406 no no no... D cell batteries?... C cell batteries... I haven't seen a use for them in twenty years. I print the screw tops... Then attach 3D printed labels on top. AA AAA...

Printing two AAA containers right now 3 hour print. On my CR10... That would have taken 14 hours...

I'm in 3D printer heaven.

Hell since switching to lithium rechargeable AAA (constant 1.5v output) I'm just using adapters for even AA.

With all my blink cameras... it feels like I go through 40 AA each month... I have very nice Rechargeable Lithium for those.

Got to test my filament runout and filament swap just now... these are AAA containers. The Mrs uses a lot of those for work. Also rechargeable Lithium

Wife asked for a gift card puzzle box for one of her bosses, my ******* is unable to just print a normal basic one that's done in a couple hours

So here is a more "simple" version that reportedly only takes 17 steps to solve. At least with the bigger build plate on the Bambu H2 I was able to put it all on a single build plate:

If you're interested there are a lot more similar style puzzle boxes by the same person

15 hour print, 666 grams of material, in this case across 2 filaments and a support material

I was a bit leary of putting a sharp corner that close into the build plate corner at the front/near the door....I might have been right about that:

printbed.png

In the app you're able to skip parts midprint so that part got skipped, the rest of the parts look good from what I can see. I'll reorient the parts around to try and leave the front corners of the bedplate more open before I upload the print profile back to Makerworld where it came from. Hopefully some finished pictures of it tonight

Has anyone see this dryer? Seems pretty cheap, but looks kind of sketchy to be honest. I debated making my own high temp dryer by putting a PID and a solid state relay in a toaster oven, but these guys have already done it. Of course I found this after ordering a Sovol SH03 which seems okay, but it doesn't get hot enough for some engineering filaments.

Kind of sketchy? Nah, just the right amount of sketch.

What filaments are you running that need to be dried above 70C?

It looks rather nice. But it's big. I have the Sunlu single. It's small enough to fit in the space allotted on the bench, and allow me to cut 22 foot stock in half.

Nothing yet, but I just got a printer that will allow me to print such filaments. I want to be able to print just about everything.

Earlier this week I had a piece of glass pull right from the surface of my Carborundum glass plate after a PLA print. I know you should always use a release agent for PETG but I had read and heard that it was unnecessary with PLA. I now use a release agent for all materials on my glass beds and I have 2 others, so I just flip this one and use the smooth bottom now, but I do have a PEI plate arriving tomorrow. Should I use a release agent for PLA and PETG on a PEI plate?

I have always used aquanet for pla or petg, even small abs parts

Possible fixes:
Increase build plate temperature
Allow build plate to stabilize about 15 min at temp before starting print
Switch to a smooth build plate

A quick way to get the plate to cool is to put it on your stone or quartz countertop. They'll **** the heat out of it quickly and you'll hear your parts releasing

I've been known to put my build plates in the fridge or freezer to get a print of really quickly!

I the two weeks I have been printing, no.

:)
Wonder if the print sheet material matters for that method.... in my imagination a glass print plate wouldn't take too kindly to that, while a metal plate probably wouldn't care. I'm also thinking about my cooking sheet pans that will twist out of flat when they get heated up in the oven, but go back to flat once cooled down again. :headscrat

I'm no rocket surgeon, but I'd bet a dollar that a build plate in full contact with a room temp stone counter will **** heat out faster than putting it on a shelf in the fridge or freezer

I'm using pei coated steel...is printing on glass still a thing?

I'm definitely not trying to argue or say my method is better than yours, but I have to disagree with that statement. The build plate probably only contacts the counter at a few very small points while most of it is actually insulated from the countertop by an air gap. In the freezer, then entire surface of the bottom side and most of the top side is exposed to really cold air, cooling it quickly. Plus, there's usually a breeze to keep nice cold air in contact with the plate. My freezer always seems to be blowing frosty air all over the place every time I open it.

Not trying to argue either. This is how friendly bets start

Air is a pretty terrible conductor of heat and when I put my plate on the counter, I hold it down. It's definitely in good contact.

Besides, my freezer is so stuffed full of **** that I could even get the plate with any decent size part in there anyway :)

Either way, it works quite quickly and I have countertop next to my printer, while the fridge is two floor away. If the fridge/freezer is working well for you, send it

Coming off the bedplate, filaments are both Bambu PLA, gray and a blue silk I believe

The lid is the part with the failed corner, it got reprinted

box2.jpg

Came out pretty well. Was running a .6 nozzle and .24 layer lines, if I was to do this or something similar again with this decorative of a pattern I would change down to a .4 nozzle to help improve the first layer appearance. It's not a cheap print as material was 666 grams.

I did give it to the wife who promptly broke it...much to my annoyance so I have a piece reprinting right now. There is a slide piece on the end that has a "pin" that has to slide up/around thru a maze pattern to be able to move other pieces, do it in the right sequence etc. She forced it a bit to hard and snapped the slide pin off, shear failure of the print. So I lowered line thickness, upped walls and a pair of them are printing again so I'll stick an extra in the box in case it breaks again.

I will admit...these are kinda neat....I might have to try a couple more
