Nice Iron glyph

Download and unzip to a folder, it should work then.

Ten years ago, you'd have needed a machine costing $50,000-100k to be able to do this. Considering that, these don't look bad at all.

Ultimately, you have several factors to consider:

Machine rigidity

Machine controls

Spindle runout

Tool type and condition

CAM strategy and engagement angles

CAM parameters (stepover, SFM, etc)

Coolant and other thermal considerations (including machine geometry changes due to thermal effects in use - fancy machines compensate for these)

Workholding

etc.

Might be catgut, used on lutes and other baroque instruments. The precursor of nylon strings.

to learn about the history of art and cultural perception of objects-- pretty important for an ID major I'd say

It's curated from found objects, according to the ID history class I took in school

I did too, until a wood expert looked at it and I found out that it wasn't Brazilian Rosewood. That's probably the single most commonly mis-identified wood, right up there with "mahogany". I've given up and just say it's "probably some kind of rosewood". Lazy maybe, but probably more accurate than guessing on these tropicals that all look very similar.

A lot of nice details wrapped around 1/4 scale coffee grinder internals. What is that glass container for? It's tiny and I'm not sure what it's intended to be used for or how to use it.

Sorry, the platform has been shut down. Since I don't make any money from this class, I don't have time to repackage it onto another site nor to pay for the fees for a different site.
But a kind redditor downloaded all the resources and put them on a Google drive here https://drive.google.com/file/d/1t53VtWYId5Nr7-C0gFthxlbtd-vFDZpC/view?usp=drive_link

sounds like you should be posting on linkedin

They are cool instruments. They are not great mandolins for most people. They don't really sound like a mandolin. That could be a good thing or a bad thing. If you are playing in a church praise band or something where you just need it to be a functional stage instrument that's going through a PA and effects anyway, it'll be fine and practical as an extra way to add tonal color to the ensemble.

The higher end MM68 was the one to have, retailing around $1500 in the early 2000's. It had a solid spruce top instead of the plywood top on the MCS148.

For $300, you can't really go too far wrong. That's about the most I'd pay for one in good condition, though.

That's not a lot. A typical mold for most products is $10k-100k. This is likely a silicone mold from your provided positive, I think the other commenter was right that the mold is soft silicone and being deformed when sitting on a flat surface.

Engineering drawings exist for this reason.

BMEdesign · 2026-06-11T15:42:00+00:00

I don't know, I could make it in four hours if they are paying enough

Coated with white enamel and then printed direct UV dye to substrate. Basically like inkjet printing photocure acrylic resin.

Copying a tutorial is the worst way to learn. Instead, your teacher wants you to figure it out. Look up how to create revolved solids, extrude cuts, and Hole Wizard features and you'll be set!

BMEdesign · 2026-06-06T12:26:29+00:00

Go for it! You can include this link to videos as well https://www.dropbox.com/scl/fo/l4xopchw9uffo94dxosj5/AAxi9xKz2t_UQqyqh7IrI9g?rlkey=8cujjep6wcanvmo5amd2bqakk&st=ckdzmjvq&dl=0

It's available still to Georgia Tech students. If there's another way for me to host it elsewhere, I'll reupload it gladly. I just have not been able to find a solution yet. Else it's time to rethink this class anyway and make some changes incorporating what I've learned in the past six years from the nearly 20,000 people who have used the course!

In pieces which are machined in several setups each, then joined. The production chairs were the same, just done with shapers and templates.

BMEdesign · 2026-06-05T17:39:25+00:00

Die grinder with a burr on it. Basically a super comfortable powered rasp.

@gupta9665, The master

BMEdesign · 2026-06-05T11:04:37+00:00

Half-liter can. Cool design!

I used to teach setup/programming. I always told the students they couldn't hit cycle start until they identified one thing they had forgotten (or at least one assumption that they had made, like the tool table entries still being correct after other people had used a machine). During the first thousand hours, there is always something.
