Stamp, Rattle & Roll Modular Rolling Pin with sensory rings and sounds

    Stamp, Rattle and Roll is a fully 3D printable sensory toy designed for children from the age of 3.

   It combines, rolling, stamping and sound in a modular system with interchangeable texture

   rings for creative play with dough, clay or sand.

   The design supports different developmental stages - from simple tactile exploration to detailed pattern       recognition and creative storytelling.

   Some rings include internal chambers that can be filled to create a gentle rattle sound adding an extra         sensory dimension.

  Key Features

• Modular System  Swap rings freely to create new combinations with patterns spacers and cutters           (older children)

• Easy assembly  Child friendly self-aligning screw mechanism. A 5mm guided insert allows children to easily align and start threaded connection without frustration.

• Age-adaptive textures     Simple/chunky patterns for younger kids. Detailed scenes for older children

• Optional sound feature    Hollow rings can be filled for rattling e.g Solid rings included for faster printing.

•  Stamp functionality  Selected rings can be used as stamps with no need to be inserted in the rolling pin

•  Left & Right Handed design  for intuitive assembly. Only one side needs to be unscrewed to change or reorder the rings. One side screws left the other one to the right. L/R clearly marked on parts.

• Customisable   includes optional parts like spacers, cutters, and plain rings for your own designs.

• No metal parts. No gluing    Fully 3D printable system

  Assembly

•         The rolling pin uses a chunky threaded system on both ends. One side is Left-Handed (L) and the other  side is  Right-Handed (R). All parts are marked.

• The handle is "trapped" between the rod and the lid and  enables the aligned screwing between the two parts.  Insert (push) rod to the handle, screw the lid. 

• After printing,  remove thoroughly any  stringing or  supports  leftovers before attempthing to screw the parts for the first time. Screw and unscrew a couple of times  and after that it should be soft enough for a child to do it. 

• After one handle is secure, the rings can be slided onto the hexagonal rod. The hex rod ensures that the rotate together and do not slip. 

• In case you end up with pretty tight rod to handle connection, consider slightly sanding the rods hey faces that enter the handle.

• TIP      Use a mix of wide-narrow rings, Sound and solid elements, to create the most sensory experience... or just let your kid decide. This is why is made for after all...

           Assembly age recommendation  

•   3+ years           Can assembly with some help. Can push and start screwing naturally. The 5mm guide makes it almost intuitive. (You could help by gluing the one end so it can open only Right of left handed)

• 4+ years              Fully independent. Can swap rings and reassemble confidently

• 5+ years               No limitations at all. Will experiment with combinations. Using the finer patterns,                                    create story lines etc

  Printing Instructions 

• Designed for easy printing without supports

• Only the rod has some minor built in supports (a file without built-in supports is included)

• 3mf files are included and they have some extended settings in order to skip supports or to achieve best threads possible.

• The sample is printed with PLA and PLA +

• All parts are printed with 0,4 nozzle 0,2 layer except the rod which has 0,16 layer height 

• Infill is in most parts 15% gyroid. 

• The perimeters vary from 2 to 4

• Sound Chambers  The rings that can be filled have a pause in the 3mf file. I used small PLA fillament scraps and tiny beads. Make sure they all fit inside well with no parts sticking out.  Experiment with the sounds. DONT USE SAND having the fans running!!!!  Note that the chambers increase printing time significantly. If they are intended for older children you might want to go with the solid ones.

• Plain rings are included so you can emboss names or letters or engrave custom patterns. 

 Design Notes

• All rings use a centered hex hole for alignment and torque transfer

• Different ring widths allow flexible combinations. The files include 2 sizes. The rod fits 5 thick ones or 4 thick 2 thinner or you can combine spacers and/or cutters in between.

• In case you d like to expand the collection of textures patterns etc. make sure that the outer diameter is ca 49mm otherwise it wont roll smoothly and some imprints may be lost. Or you could ofcourse design 5 or more rings with same custom size. 

• This system is designed to grow together with the child giving space for numerous ideas. It was really fun doing it and I hope that many more patterns will be added in the future. 

                                           SAFETY NOTES  

•   This model is intended for use under adult supervision, especially for younger children

•   While the design avoids small parts, print quality depends on your printer and settings                                        

      The user is responsible for

•       checking all parts for sharp edges, loose strands or defects.

•       proper post-processing and cleaning (removing stringing, supports, debris)

•       Ensuring all components are securely assembled before use    

      For rings with sound chambers use

•       safe, non-toxic, filler materials

•        ensure the chamber is fully sealed after printing

     Do not use damaged parts 

      Not intended for chewing or as a teething toy

      Also consider the limitations of PLA

     Have fun printing and rolling!
