Noise-Canceling Chewing Gum Case (parametric)

This is a pocket sized travel case for chewing gums designed to fit extremely snugly so that the gums don't rattle and vibrate making noise when walking.

The box in the model is made for 6 gums size 21x7x10.5 mm (daygum protex), if you want to have a different size i included two Inventor files with all the dimensions as parameters so you only need to measure your candy to get a custom-made case (instructions down below).

Measure the gums with calipers and put the exact value in the parametric table, inevitably some gums will be smaller and some bigger so you will need to use a bit of force to get the bigger ones inside, this is normal and the holes on the bottom are there to fit a corner of the lid trough to push and free stuck gums. When you empty the box wash it under cold water (and soap if you want to) before refilling

PRINT SETTINGS:

If you don't use my profile make sure to use at least these settings so that the lid fits smoothly:

• set wall generation to arachne
• set layer height to 0.12

And to get the same surface as the one in the photo set top surface pattern to octagram spiral and add height range modifiers to make the handle and the top of the box monotonic.

PARAMETRIC INSTRUCTIONS:

If you have a copy of Inventor you just need to download the two files and open them, then

1. With case.ipt open go to the Manage tab
2. Click on Parameters
3. Scroll down to Local Parameters
4. Edit these parameters:
   1. sp: wall thickness
   2. handle: length of the handle portion of the lid
   3. width, height, depth: the three sizes of the gum
   4. count: how many gums
   5. hole: size of the hole on the bottom, edit if you change the width
5. Save
6. With lid.ipt open go to the Manage tab
7. Click on Update
8. One file at a time click on File → export → CAD format→ STEP file
9. Download and open my 3mf file
10. Right click on one of the two objects → Replace with STL → select the corresponding STEP file (lid to lid, case to case)
11. Print

If you don't have a copy of Inventor you can use the free trial. or monkrus iykyk

I briefly tried to import it in Fusion 360 and edit the parameters there but i don't use it very much so i couldn't find the options, if you get it working send me a pm or leave a comment and i'll post the instructions here.
