Post-Printing

Step 1 - Inner Tube

Print parts
1x InnerTube
1x Decoration
2x DecorationStub

Also need
8x bolts M3 Len=10mm
8x nut M3

Superglue for connect:
Decoration + DecorationStub (each with M3 nut)

Step 2 - Outer Tube

Print parts
1x OuterTube
1x OuterTubeStub
1x OuterTubeGlyph
1x Decoration
2x DecorationStub

After print:
!!! check for free movement of each gragger
if the movement is complicated carefuly remove superfluous with a knife

Also need
2x bolts M3 Len=10mm
2x nut M3

Superglue for connect:
Decoration + DecorationStub (each with M3 nut)
OuterTube + OuterTubeStub

Step 3 - Rings

Print parts
6x InnerRing
6x OuterRing

For each ring must be plugged both inner and outer part
Key hole under password symbol

Step 4 - other

Place rings into outer tube
Screw OuterTube and OuterTubeGlyph
Screw Decoration and Inner/Outer tubes

How I Designed This

Inner/Outer rings

Letters and normals in Outer ring

Inner ring

Ring assembly

Outer tube

  • design Outer tube segment for rings
  • design Outer tube with 6 segments
  • add missing details

Inner tube

  • design Inner tube segment for rings
  • design glyph ring
  • design Inner tube with 6 segments
  • add missing details

Back part of OuterTube

  • design glyph with holder for back part

Decoration

  • design decoration shapes
  • make hex nuts holes inside
  • design stubs for ficsation of nuts

Project

Objectives

Ability to understand:

  • mechanics of moving parts.
  • logic of admissions and accuracy.
  • the basic principles of mechanical hand-made articles.

Audiences

Basic grades:

  • 3D Design
  • 3D Print
  • Math
  • Physic

Preparation

Students have to have interest in riddles and puzzles.
Students who isn't afraid of difficulties and shows interest in the new.

Steps

Analytic:
1) try represent in mind each standalone part of this thing.
2) think how to join each part with other
3) think about dimensions between parts
4) think about movements of parts
5) think what parts need to be changed if need different letters for other language
6) think what need to do for change ring count

Design:
1) try clone this thing, part over part
2) try make an different language rings
3) try make an different ring count

Before printing
1) try think about fillament on each layer when it will be printed, as far as it will spread in the parties.
2) try to consider physical properties of material if it is necessary return to design.

Final:
1) after print and assembly, gift your friend this thing

Now you became cleverer and you can tell - I am able to do it!

Results

Goals:
1) think before print / do something
2) open mind for new ideas
3) learn different language letters / codepages (utf-8)
4) search ideas in different knowledge areas
5) try combine 3d design and 3d print skils

Hi, did you read summary?

Additional requirement:
10x bolts M3 Len=10mm
10x nuts M3

A really great work.
And i hope you will have time for the 26 letter ring soon :)

I think about at holidays =)

cool this is (yoda)

I'm not good with editing/creating these types of files, is there a way we could get an English/26 letter alphabet ring file?

Hi, this is same to rebuild all thing for English/26 letter alphabet.
It is possible, but at now i don't have free time for this.

Excellent work! How to set the password?

Just change positions between outer and inner rings...
Inner ring have special key-hole
