I shared a 10mm cube on thingyverse for someone that asked for it yesterday. It’s had 11 downloads 4 likes and 2 collects. I didn’t think it would be so popular (as in why would anyone download one) . Go figure right??? anyway if you want the most mundane test print ever get it here http://www.thingiverse.com/thing:1006277
New postings grab attention. If you are given the choice of a one day old item or a one year old one which would you choose? It’s human nature to go for the newest.
I have the same idea, as I use my own test models for quick settings prints, but never have a courage to publish it. 
Your cube is a thing of beauty. Very few have such skill and finesse…
I know I didn’t chamfer the edges or anything.
If you like I’ll do a 10mm sphere to match. I’ts also a default object in freecad.
If I add a polygon it might end up as a featured thing on there they seem to have a way to find obtuse designs.
After spending 6 hours designing a intake tube for a race car, I can only shake my head.
Screw it I’m going to print one and post a make. Maybe we can tell people posting really bad benchy prints to set their sights a little more realistically to start with.
So I don’t think I’ve ever actually printed a 10mm cube till today. its a little harder than you think. My first go didn’t go as well as I thought it would. So here’s the updated description. Turning the most mundane object from a joke into a challenge.
Description
Deceptively simple this is a 10mm cube. There is no room to hide only facts. If you choose to print this the measurements wont lie it will need to be 10mm high 10mm wide and 10mm long anything else is a failure.
Post your make and prepare for merciless critique
The idea is to print it in your best resolution layers. Its small enough to do it. Any printer has to be able to print this from the smallest to the largest. (OK maybe not those a concrete printers, but they will suck at Benchy too)
The small size means overheating the print will be an issue that will limit your layer height,
Print it in easy to see colors show the top and the bottom, show it with a caliper for size.
Oh its not for calibration. I use a 80mm radius with a 50mm cube cut out as a test print and measure movement over 200mm for initial calibration. This is simply a print to show you can, I thought is was stupid till I printed it because its so small flaws are magnified. - go on print one and post it, its 10 minutes out of your day and you’ll see what I mean. to slow its going to overheat and disform to fast and your corners are going to overrun , so you increase layer heights to help but the challenge is lowest layers you can, and at the end of it it needs to be 10x10x10mm.
Kind of funny that you literally posted an stl file for a 10mm cube instead of posting:
cube([10,10,10]);
If someone asks for a 10mm cube, what do you think the chances are they use openscad.
Mabe a fuzzy interpretation of benchy
Clearly the chances are less than you attempting to teach them openscad. Give a man a fish…
