Following the directions from my images, it should be pretty straight forward to make your own motorized dolly.

But remember this requires a few more tricks than just 3D printing:

Buying parts online, most of them on ebay
Getting small fasteners
Machining pulleys to fit bearings
Soldering cables to motor

Luckily, everything is explained!

Step 1: BOM

Here is everything you will need to get to succeed.

STL Files available here as well as a pdf file with hyperlinks.

Step 2: Clamp

You will need to build 2 clamps.

Step 3: Carriage

Build your carriage.

Step 4: Motor

Assemble the motor and its gears.

Step 5: Further Details

Here are more details to help you to succeed.

* Belt length is 1990mm *

Step 6: Get Out There!

Go try it!

I used :

Magic Lantern on my EOS 7D for setting time-lapse
LR Timelapse & Lightroom for editing
After-Effect to render the video (sometimes I used a warp stabilization at 1 or 2% because of the wind..)

Good luck'

Step 7: Videos

<p>I'm very interested in making the Travelapse, but all links to ebay give an error... Do you have a better description of all needed materials?</p>
<p>I will update this list yes, but the battery doesnt exist anymore, the easiest is to with an external usb battery that gives you 5v output only so you will only have the two slowest speed. Cheap, easy and its working.<br><br>Do you have a 3D Printer? I'm printing a bunch of them right now if you want.<br>Will update thing here and on facebook next week!</p>
<p>I will probably have access to a 3D printer, but still have to check. I'm probably interested in the printed parts. I'll keep an eye on the facebook page (and this page).</p>
<p>Send a message to my facebook page and I will give you a few options! ;)</p>
<p>Oh - if anyone is looking for cheap bearings - look for used old pairs of rollerblades :) usually they use 608 bearings, 2 per wheel = 16 bearings per pair of blades. I picked up 2 pair of blades for $10 through local kijiji/classifieds.</p>
<p>nicely done! I'm building a slider too, but the final finish isn't as refined.</p><p>Is there no control yet for the motor? just plug it in and it starts moving? I'm attempting an arduino uno based shoot-move-shoot system. Slow going in between other commitments though!</p>
<p>I don't understand the speed description. At 5V the short gear is faster than the long gear. At 9V, the long gear is faster than the short gear. Why do the gears work differently as the voltage changes? Other than this question, this is a remarkable Instructable. Thank you.</p>
<p>a haha thanks for spotting it, you're right there is a mistake. long gear gives you a slower speed than the short speed. and if you increase the voltage you increase the speed.<br>So my table should be <br>Long Gear - 5v - 3.5 h<br>Short Gear - 5v - 2.5 h<br>Long Gear - 9v - 1.5 h<br>Short Gear - 9v - 15min</p><p>Thanks for reading : )</p>
Thats awesome keep it up and thanks for sharing?

Wow I love your presentation! Did you render out all those images? Is the real thing quite like you plannen?
<p>I used Solidworks for rendering, I thought it gives a pretty cool presentation ?</p><p>The result is pretty good as well, I print in ABS, and do a quick acetone vapor finishing.<br>I've uploaded a picture of my prints in the comments ;)</p>
