Beer Mug Transport Container

There's a story behind this.  While camping, my friend's favourite beer mug was on the picnic table, and his RC car next to it.  I picked up the RC controller, and inadvertently caused it to drive the beer mug off of the table.  The mug shattered.

I obtained a replacement mug on eBay, but having just bought my first 3D printer (MK4) I decided I would prevent such a thing from happening again.  This is my first creation.

I reprinted the base and top to fix some serious issues with integrity of the assembly.  Obviously this will only fit this exact size of mug so you'll have to remix to fit whatever you have.  The good news is I developed this completely in TinkerCAD so it's an easy remix.

Changes from the original:

• Base and Top are now v3 - middle section hasn't changed.
• Constriction at bottom centres the mug and protects the hold-down clips.
• Total of 6 hold-down clips, printed twice as thick to provide better grip on the mug.
• Copied the latches from the Parameterized Rugged Box to hold the 3 parts together - provides a much stronger and reliable connection.
• Gyroid fill on all pieces.
• Removed the slots for the old latches and the “tool” since they are no longer needed.
• Provided the top plug (that plugs the hole in the top where a straw can be inserted) as a separate model.

Print parameters used:  0.2mm layers, 0.4mm nozzle, 15% Gyroid infill, support on base plate only (top and bottom pieces), Prusament PETG filament default parameters

I printed this using support on base plate only, and painted support under the handle (both top and bottom pieces) and prevented support for other areas that popped up.

To build latest version:

1. Print base_v3, top_v3, and middle sections.
2. Print 2 latches
3. Print top plug from the stl file
4. Print Badge1 and Badge2 (2-color prints to get the text)
5. Use (4) M3-30mm bolts for the latches - hinge at the top, top bolt inserts from the left, base bolt inserts from the right (sorry about that).
6. Glue the badges into the depressions in the middle section.

Things I would change:

• I mistakenly deleted the constriction at the bottom that would center the mug, which resulted in one of the hold-down clips breaking.  It's in the model, I just didn't protect it when putting the hole in the base.
• The hold-down clips are too weak - placing 6 equidistant around the base would hold it very well.  This mug has a 12-sided bottom that is concave so that helps a lot.
• The clips holding the 3 parts together are too weak and let go too easily.  This might actually increase the chance of breaking the mug…  Lesson learned, never use a 1mm thickness for anything useful.  Right now I'd use a short rope or bungee to lash it all together to be safe.  Then I'd remove the clips altogether (they can be removed by inserting the 1mm thick tool down inside the hole to release the tab)
• The “badges” should have been flat on the back, and the badge indentations as well.
• I used hexagonal fill on the base for the print - a mistake, it took forever and used a lot of filament.  I'd use gyroid next time.
• The “tool” that inserts into the top handle doesn't fit because the slot isn't high enough - should have been 5-10% bigger than the tool.

Print parameters used:  0.2mm layers, 0.4mm nozzle, 15% Gyroid infill, support on base plate only (top and bottom pieces), Prusament PETG filament default parameters

Print the base and middle section right side up.  The top should be printed upside down.
