imgur.comThey make pencils with spring-loaded lead, which makes the lead much less likely to break.
I'm partial to Alvins, but I've seen similar designs from other companies.

Iām gonna be that guy and say itās more like over ādesignedā not over āengineeredā. Thereās way more material than whatās needed to support the pencils, and the ergonomics looks like it can be improved.
Show us how/where you iterated the stress analysis or ergonomics for the engineering nerds?

*Under-engineered.
Making something stronger than it needs to be by guessing and throwing excess material on the part is not engineering.

You must not know about finite element analysis or generative design... :P

Thanks for the input. That's an interesting point. I guess if this person was some type of engineer that is unrelated to the design and fabrication of parts/pencil holders they could have still engineered it in some way. They could have used surveying equipment if they were a civil or geo-technical engineer, to ensure the boundary of the part was within the legal zoning. Or, if they were an electrical engineer, they could have tested to make sure there wasn't a capacitance of the material that would discharge dangerous amounts of power into someone's heart...

Overly engineered? Maybe...
Absolutely beautiful? Absolutely!

subtle https://littlemachineshop.com/ plug? I approve.

Yea... I just bought a 3 inch vise for my mill. I probably shouldn't have done that

There's nothing wrong with it. I was just joking.

I call shenanigans. How the hell do you lose a CAD file?
Here are the files
OP DELIVERS! Doing God's work here!!
I'm going to print this on an Ultimaker this week and post pictures! Thank you VERY much, and I sincerely apologize for doubting you!!
20 prints for slytherin!
I found the file. I can post it as a STEP that has all three parts. I'm old- so I don't really know a good place to post the file. Any good ideas?
Thingiverse maybe?
That would be super cool, thanks for looking! Definitely like the idea and your execution was very very slick!
How large is the STEP? I could give you my email address over a PM if it's smaller than 25 MB.
Otherwise, if you have a dropbox account you can put it in your dropbox folder and make the file public. That would give you a link share the file, but if you don't already do dropbox I don't want to ask you to go through the sign-up and install process (although it is a pretty slick service, free backup online for up to 2 gb. Saved my butt when I suffered through a crash & stupid accidental delete.)
Maybe just unwilling to share it, which is fair enough.
That I would completely understand. Sounds like dude found it after all.
Nope- really sorry though. š I might check my Trash on my computer. We are watching Stranger Things. Will look after
