The door knob was a surprise, 10,334.72 cubic millimeters. I suspect the reason is that it is COMPLETELY solid. Many things that look solid are not. There is generally a "fill" pattern that puts just enough filament in a slice to support the filament of the next layer. A fill can be as little as 20% of the volume of a truly solid layer. Then two or three solid layers are laid down to complete the piece. I would not be surprised if the fill of the knob is 100% to strengthen the screw hole to mount the knob.
Many of the Freedom of Creation designs use this dual layer asymmetric hole pattern. It's ingenious. This not only keeps this relatively large object at a modest filament requirement of 10,427.24 cubic millimeters; but, it's very strong. I would love to know how much experimentation went into coming up with that pattern. It is WELL worth studying if you plan to design items like this.
The Rook, at 16,285.88 cubic millimeters, is probably the most famous 3D printed item of all time. Everyone goes gaga over the rook. Not a single person has ever turned one down when I've offered one to them. And, they are amazed at the steps and the spiral in the center, which can be viewed from from several vantage points.
I was no different from anyone else when I first saw it. Yes, the stairs and the spiral were impressive. But, even MORE impressive to me was the smoothness of the wall and the preciseness of the brick pattern! This is a MUST PRINT item. :)
Fully functional, the Nano bracelet total filament volume is just 17,993.35 cubic millimeters. It's the first piece that I gave to my oldest granddaughter. It works! This seems to be another one of those pieces that draws a crowd at shows. For me, aside of the ingenious pattern of irregular holes is the hole if the top that helps in the removal of the Nano. So, don't worry, your Nano won't get stuck in there! :)
Look VERY carefully at this little beauty. I'll be glad to part with 18,747.96 cubic millimeters of filament to see how this prints out. But, not in Neon Green! I'm waiting for my other colors for this little gem.
- BraceletMacedonia_D57_Medium.Creation - 18,779.13

The volume of this one, 29,034.22 cubic millemeters , surprised me. But, that's probably because it, like the door knob, may be completely solid. I wonder if it doubles as a magic wand. I have some relatives that would make good frogs! Hmmmm.....
This bigger version of the Nano bracelet comes in at 29,548.5 cubic millimeters. It looks solid enough to use as a weapon! That thing looks HUGE! I'll let you try it. Let me know how it prints.
Now, we are getting somewhere. There is nothing that warms the heart of an aging country boy more than a good slingshot. And, this one looks a WHOLE LOT better than the ones I made as a...uh.. er... troubled youth. I'm MORE than happy to cough up 40,615.85 cubic millimeters of filament for this one!
And, did you see that fancy pull handle? That's just downright luxurious! Now, remember boys and girls. Please play with this one safely. Be sure you have a clear exit path before you shoot your older sibling! 'Cause, you're only gonna get ONE shot before you look like Beatle Baily after the Sarge caught him! Run fast. Run VERY fast.
It's a good thing my mother isn't alive to me with this one. She's tougher than my oldest sister! (Who is WAY tougher than my brother!) Yep. She'd be stomping on that thing. She'd give that ABS plastic a good endurance test! WHOAAA!!!
I definitely plan to print both sizes of tea cups. It's a must do for a grandfather. A set of four won't take too much filament because each one is 40,863.35 cubic millimeters. Of course, each cup will have to be printed in a different color. But, fortunately, there is very little waste with the Cube when changing from one color to the next.
Frankly, I'm not at all sure about these next two. When I was six, my home was surrounded by a brush fire. I remember running down our long dirt driveway with fire on both sides of the drive. So, I'm probably a bit more sensative about fire than I should be. But, please be careful if you print out these last two items and watch them carefully as you use them. At 46,283.52 cubic millimeters, it's not terribly hard on the filament budget. But, it's not one I'm likely to print out beyond one or two tests.
Here again, my personal experience, leads me to not trust mixing candles with ABS unless one is very, very careful not let the flame lick at the holder. Both are perfectly safe if used correctly. But, experience tells me that people don't always use things correctly. Please don't be one of them.
At 57,566.11 cubic millimeters this is the last of our under 60,000 cubic millimeter group. I hate to end this post on such a downer. But, I would hate to dleefully encourage you to print these out and leave all over the house with a burning candle unattended. I like people smart enough to be Cube owners and I sure don't want any of them hurt. BE SAFE!!! :)
Another nice and good information.ReplyDelete

Thanks! My goal is to help all of us have the most enjoyable experience possible with our new Cubes. And, the more we know, the better choises we can make.ReplyDelete
I really appreciate your comment! :)
I am currently waiting for my cube, and asked them about the plastic and food safeness. I was told "I would not recommend using the plastic for food applications. You can never be too safe!" which then surprises me they include a tea cup in their free designs.ReplyDelete
ABS is routinely used for food containers, etc. So, in a general sense ABS might be considered "food safe". But, in a specific sense, there is probably no way to know if a supplier of ABS filament is careful enough with every batch to make that claim for filament for a 3D printer. So, that is probably why they responded as they did.ReplyDelete
