Introduction: Christmas Tree Monorail

Picture of Christmas Tree Monorail
This is a custom designed monorail for use about half way up my Christmas tree.

Step 1:

Picture of

Print the track and all the other plastic pieces.

Step 2:

Picture of

Insert a hose washer (drive wheel) around the drive spool.

Press fit the drive spool onto a Pololu gear motor (Jameco #2128219). Press fit the motor into the slot on the drive base.

Step 3:

Picture of

Glue (superglue) a AA battery holder to the printed base. Connect and solder the wires.

There will be no switch. Installing and removing an AAA battery will turn the device on and off. The AAA battery in the AA holder is easy to put in and out.

Step 4:

Picture of

The track pieces need to be joined (print 12 pieces).  I "welded" the PLA plastic together with a soldering iron (outside, it can get smelly). They can also be joined using metal duct tape, but that's kind of distracting visually.

Step 5:

Picture of

Paint a 1 inch by 2 inch by 38 inch piece of wood (I used oak).

Step 6:

Picture of

Fasten the wood to the tree using deck screws and the printed bracket.

Step 7:

Picture of

Slide the end pieces onto the wood.

Step 8:

Picture of

Place the track on the brackets.

Step 9:

Picture of

Secure the track with 2-56 machine screws (available at Radio Shack).

Step 10:

Picture of

Add the tree branches. If you cover the oak cross brace, the monorail track will almost appear to float.

Step 11:

Picture of

I scanned a clay snowman and printed him in plastic--merged with a monorail "top."

Step 12:

Picture of

The plastic snowman was painted for visual appeal.

Step 13:

Picture of

By using the plain monorail "top," it is possible to attach (with velcro) any small object that wants to ride around the tree.

Step 14:

Picture of

Put a battery in the monorail base, then snap on the top and let him ride.
