Russian Doll Maze VariantBlind

in 3D Printing Design held by JT Customs
Contest Ended, Winner(s) have been selected.
Hello Designers!

I am looking for a variant of the "Russian Doll Maze Puzzle" on Thingiverse. Here's a little bit about the project:

I run a small home business in Utah that provides 3D printing services for the local area. Lately, we've been donating our extra machine time to making these puzzles for charity (Anti-boredom bags for children in hospital waiting rooms.) They've been a massive hit among the kids, however we've been hearing that the locking mechanism is 'unsnapping' over time while the puzzle is assembled, making them inoperable. We'd like to remedy that for the future!

A few required design change specifications:

1. Cylindrical instead of Octagonal
2. The maze "Locking" mechanism needs a fix. Currently, it snaps "Up" into position, however the clicking mechanism is small and wears down, resulting in older puzzles 'locking' inside because they've come undone. We're looking for innovative solutions to solve this issue (potentially rotating sideways at the end, instead of up, to add another safety mechanic)
3. Thick bottom and outer wall for embossing names, if chosen. Needs to be strong enough for children to not break with regular usage.
4. Difficulty of maze appropriate to 8 and up age levels.

Dimensions overall approximately 4" height, 2 1/2" round. 1/8" to 5/16" inner wall construction (solid).
1. Style and complexity of the design.
2. A maze design that is challenging.
3. Easily printable without supports being necessary.
4. Smooth interiors on the puzzle - tightly fitted.
5. Thick structural sides on all pieces of the puzzle.
6. Room for enclosing small items (notes, money) internally within the puzzle.
7. Sturdiness and tightness of the design. We're looking for a smooth experience that is difficult for a child to break - pieces need to be durable and snug.
Don't Wants:
Same design as already provided.
Similar just not identical with modifications provided above.
Too small to enclose items (rolled up notes, bills)
Too Large as to be hard for small children's hands to hold.
  1. Autodesk Fusion 360

Hi. Here my offer for you. Of course is just the first layer for now, just to see if I`m going in the right direction. Attached the files for test. Feedback is welcome.

his is just a preliminary design. I have only completed the outer case and the first layer of the maze, but before I went further, I wanted to get your impression to see if my design is developing the way you would like. Please let me know if the files I have included are enough or if you need something else. Any input you could give would be greatly appreciated. Thank you.

Here is the final file. For the exterior maze, all the paths are open now. The inner one is a lil more easier because of the limited surface to play with. Also the inner have just an one direction lock because must be just one precise lock position to allow the cover to leave the maze through the channel. And of course the map for each maze can be provided for the printed instructions.

Hi JT Customs – This is my completed maze design. I have made some minor modifications to the first layer from my preliminary draft, and completed the second &third layers, as well as the outer case. Please let me know if there is anything you would like to see added or changed. All comments welcomed. Thank you.

@Ricky3DVFX & RRM

I can work with most file formats in terms of submissions. Preference is .stl, .obj, or .3mf, however I can work with most others as long as its a fairly straightforward process to export to .stl in Fusion360.

would obj. model be acceptable ?

is that ok with 3ds max file format ?

Could you provide the CAD model of the old octagonal design? It will help focus on the important things.

Super 8 film reel
I have the design made, looking for someone who can print it. Includes the reel and a core adapter. Looking for 6 of these. Maybe do more if they turn out well. 1st prize is 250 for 6 reels/core sets printed.
"They Might Be Giants" School Award
I am a local community member working with a K-8 school principal to develop a custom award for two members of their faculty to be given out each year. The award is called "They Might Be Giants" and it celebrates educators who have been the "shoulders" that younger educators have stood on. Think like a mentor, but more than that. Ultimately the creation from this contest will be 3D Printed and integrated into the final award. Think 6" - 8" high 3D giant. I'm open to ideas, but the attached pictures provides a good references of the giant idea and it supporting people on its shoulders. If you notice the male and female standing on the giant's shoulders in the reference photo you get a sense of them looking into the horizon. Where the Giant has a sense of forward motion. It is the combination of the sense of movement toward the horizon, and the eagerness to look toward the future that I to capture with this 3D element. The working concept for this award is based on an award presented by the Advertising Hall of Fame called "The Golden Ladder" Award (See attached photo). In place of the golden ladder will be the giant element that this contest is looking to produce. The total height from the foot of the giant, to the top of the tallest head of the person standing on the giant's shoulders will be no more than 8" high
Stack of Schnauzer puppies
I need a 3D drawing of a stack of schnauzer puppies (in diapers) that are placed on top of one another (alternating back and front). I intend to 3D print this out and it's meant as a Christmas present.
Dental Tool
Mass produced plastic tool for dental product. My immediate need, however is to have 3-D prints made for evaluation. I'd also like to use the same file for manufacturing. Plan of tool, logo file, detail of head and pic of possible diamond-pattern knurling grip attached.
