Money Printing System (MPS) Made of Cardboard

We have a problem: we have got little money.

Idea! We can make a Money Printer machine!

How to make a Money Printing System (MPS) from cardboard. You can learn to make it at home by yourself.

Step 1: We Must Have...

• Cardboard
• 3D Printer to create parts of the mechanism
• Polyethylene garbage bag
• Tools
• Paper

Step 2: Designing Mechanical Parts for 3D Printing

• Ratchet-and-pawl mechanism
• "no-paper" locking mechanism (left)
• "no-paper" locking mechanism (right)

Download the STL files.

Step 3: Assembly of the Device

• cut out the side walls of device
• cut the rollers
• cut the fixers of rollers
• put the rollers and fixers into the side walls of device

look at the pictures...

Step 4: Embed the Tape...

• cut the tape from polyethylene bag
• using scotch-tape, glue the tape to the upper and lower roller diagonally

look at the picture...

Step 5: Create a Locking Mechanism...

• insert plastic parts of locking mechanism (their must printed) into the side walls of device
• cut cardboard parts of mechanism and glue them to plastic parts

look at the picture...

Step 6: Create a Locking Mechanism of Backward Rotation...

• Glue the ratchet to the lower roller
• Glue the holder of pawl over ratchet

look at the pictures...

Step 7: Make a Cover and a Handle...

• Making the cover of the device from cardboard
• Cut two circles of cardboard
• Glue the circles to lower roller as handle

look at the pictures...

Step 8: Test...

• Roll the bank note under the tape of upper roller
• Cover the device the cardboard cover
• Prepare a paper tape
• Insert the paper tape into device and turn the handle of mechanism

look at the pictures...

The device must give you much money!

The more paper, the more money!
