3D Printing


Unfortunately, our 3D printer is currently out of order and we are not able to accept any print jobs at this time. Thank you for your patience.


To use our 3D printer, you can fill out the form at the bottom of this page and attach your file. We only accept STL files for our Makerbot Replicator Mini.

  • Files should be in STL format (.stl).
  • The largest design we can accept is 5x4x4 inches.
  • Objects with flat bottoms are easier to print. Designs with overhangs or very small features can be more difficult.
  • We 3D print using only PLA filament.
  • Cost are determined by the filament weight of the item printed. We charge .10 cents per gram.

If you prefer not to submit your own design, you can look through a list of 3D display items we already have files for and order one of those. The list with pictures and prices is here, and our order form for those is here.

Our 3D printing policy is available here.

How to Create a Design

We recommend Tinkercad, a free, web-based 3D design tool for beginners. It has lessons and short tutorials so you can learn the many features available. You need a valid email address to sign up.

Two other possible programs are Autodesk123D and SketchUp.
Both are free software you can download to your personal computer.

Free STL Designs

If you don't want to create a design from scratch, you can get free designs from Thingiverse, an online site for 3D printing ( You can use the search bar in the top right hand corner of the Thingiverse website to find something specific, or you can browse different categories and collections by clicking on the EXPLORE tab.

Once you have found a print you would like to use on Thingiverse, click the DOWNLOAD ALL FILES button. If you are using a computer at the Park Ridge Public Library, you can find the downloaded file in the All Patron Shared Drive located on the desktop.
