Hi Instructable users !
We are three students studying Industrial Product Design in Kortrijk, Belgium. For our subject Product Engineering we were assigned to build and develop an Art Maker for children of a local SNE school (Special Needs Education) to do handicrafts in a safe way and stimulate their creative self-development.
our Art Maker is called the Marble Painter. It is built to make patterns on textiles using various kinds of textile paint. The printing of the piece itself is done using marbles that are immersed in paint and then shaken back and forth. This way the paint gets openly coated.
To drive the system a bicycle was used. So when the child starts to pedal the mechanism gets initiated and the Marble Painter can do its work ! fun guaranteed with our "little" art machine!!
Off course some work to build but here we are to help you guys out and explain a bit clearer how we made our "machine". Every step is provided of a manual containing the assembly and needed pieces (2D Drawings).

- A full manual containing 2D drawings
- A manual containig only assembly steps
- A manual containing only 2D drawings
Step 2: First Preparations
- Saw the wood according to the dimensions of the given files.
- Make a fixture to clamp the mini bike on. This will be necessary to give the bike stability and fix it to the ground plate.(You can also buy a clamp for the bike)
- If desired you can also paint the parts (wood, steel , .....) in any color you want.
Step 3: Construction of the Steel Profile
A steel construction is needed to clamp the two ground plates. Therefore an U - profile can be made according to the file provided in the manual.
Step 4: Subassembly of the Bike
Attach the bike to the steel construction you have welded / bought. Make sure everything is clamped well by using bolts and annular blanks.
Step 5: Subassembly of the Wooden Frame
The wooden structure is needed as a base to attach the driving rod system. To make it as easy as possible to assemble everything we split the manual op in two parts : the right side of the frame and the left side. This wel keep a good oversight when working on the Marble Painter.
Sidenote : the first picture shows an overview of all the pieces needed to assemble the right side. the second picture shows the same for the left side.
Step 6: Subassembly of the Rod & Extension Table
Next thing to do is the subassembly of the rod and the extension table. The rod is needed to make a connection system between the bike and the circular stencil (which need to be fastened on the extension table).
The distance between the rod and the stencil is very important and needs to be accurate to have a good working Marble Painter. Make sure the extension table can slide until the end of the frame.
The places were two nuts are used replace in fact the safety nut due to the fact that a small clearance is needed to nurse the rod spins smoothly. Also provide some blanks as shown in the pictures.
If everything goes well this is the result you should get by now !
Step 7: Subassembly of the Circular Stencils
The circular stencils are serving as a base to put your piece of textile on. Attach these to the extension table.
Step 8: Assembly of the Rod to the Circular Stencils
The connection is made by a 3D - printed part which can be found in this step ( 3D - printable file). Make sure you use locknuts to clamp everthing as this is one of the most important steps to make a good working Marble Painter.
Sidenote : if you don't own a 3D - printer you can print the piece in a local 3D - hub using this link
Step 9: Subassembly of the Paint Rack
Attach the paint rack to the ground plate. Pay attention to the fact that you need to have enough space on the sides to attach the U - profile in a later step !
Step 10: Assembly U - Profiles + Rod System to the Ground Plate
Attach both profiles to the ground plates. Your base for the Marble Painter has now been made. The next thing to do is to fasten the rod system to this base.
Step 11: Assembly of the Bike to the Rod System
Assemble the bike chain as shown on the pictures. Pay attention to the fact that your chain needs to be fixed tightly and may not bend to deeply. If the chain bends to much it might fall of the sprocket while using the machine.
You can simple do this by moving the bike more to the front or the back of the ground plate. The bike should be centered with the sprocket to get a straight runnig chain.
Step 12: Assembly of the Bike Onto the Ground Plate
If your chain is set correctly you can attach the bike to the plate .
Step 13: Finish With Plexi Pieces
To finish of the machine some pieces of plexiglass are used for the circular stencils and the painting rack. The pieces can be lasercut easily using the file given in this step. Everything is set correctly so nothing needs to be changed anymore.
Step 14: Finishing Touch
The last puzzle piece : the Art Maker Logo !!
This is also made out of plexiglass (part of the lasercutfile) and a piece of ABS (100 x 100 mm). Attach the logo anywhere you want on the machine. This beast is now ready for a spin !!!
Step 15: Let the Fun Begin !
