Submit a 3D Printing Project

Students may submit projects to be printed on the school’s 3d printer.  Projects must either be in support of a class assignment or project, or fulfilling a need from the new St. John 3D Printer Problem Bank.

All students must attend a 3d printer orientation or workshop before submitting a project for printing.  Sign up for a session here.

Lessons learned and common problems with student projects:

  1. When in doubt, you can share your project with Mr. James through TinkerCAD and he can help advise on problems you may be experiencing.
  2. Export the project as an STL file, and be sure you are exporting everything you need, either by exporting the entire project or first selecting the parts you want to export.  Several projects have been submitted where 90% of the model is missing from the exported STL file
  3. Make sure your bottom surface of your model is flat, with nothing floating above the surface.
  4. Make sure there are no unintended gaps that will result in your object printing as several disconnected objects.
  5. Watch your overhangs, especially if they are in areas where support material will be difficult or impossible to remove such as the interior of a hollow building.
  6. Allow sufficient time for printing, the possibility of print failures and needing to reprint.  Allow a minimum of a week, more if your project has problems requiring creative solutions or re-work.

To submit a project, complete the below form and get your .stl file to Mr. James:

  • Middle School students with St. John Office 365 accounts must upload their file to their school OneDrive folder and share it with Mr. James.  Here is the navigation path: -> OneDrive -> Upload -> Share
  • Students lacking a St. John Office 365 account should have a parent share the file with Mr. James via Dropbox, OneDrive, Google Drive, etc. and email him a link at

3d Printing Request

Submit your request to have your project printed here.
  • Summarize your project in 10 words or less
  • Include number of objects, approximate dimensions, and a short description of the object(s). If the project is a mix of original and downloaded work, specify what you did to alter or add to the downloaded content.
  • How does this project support or enrich your class project? If it is a Problem Bank project, in what way will this improve the recipient's life?
  • What did you learn while preparing the 3d model? Was there a new technique you learned? Was there a skill or technique or concept you better understand as a result of this project?
  • Possible things to include here are a deadline if you have one, color preference (no promises!), and any particular printer settings you might want to specify or discuss such as rafts, supports, and infill density. Random questions can go here too!
