Introduction: 3D Print Intermatic Timer Trippers

About: I'm a 49 year old Systems Architect living in the Midwestern United States. After travelling the world for 20 years as a consulting architect I became disabled, as a result, I am now embracing a Slow life. F…

If you have ever used an Intermatic TN-series Timer, particularly for hydroponic gardening, you soon learn the frustration caused by the little plastic timer trippers that are necessary to turn the current on and off according to schedule. The most frustrating thing perhaps, is that there never seem to be enough of them in the box (typically 3 ON and 3 OFF), and a 4-pack of more of this little plastic gems costs as much as a new timer!

If you have access to a 3D Printer, you can 3d print your own in a little over 10 minutes for pennies apiece.

What you will need:

Step 1: Prep Printer and Load Files

Following the instructions included with your printer, calibrate the printer, install filament, and apply BuildTak to print bed.

*The following instructions are specific to the M3D Micro 3D Printer

Start the M3D software if you haven't already for calibration. Select "Open Model" and select the .stl file for the OFF tripper from the included .zip file. Click Print. On the options screen, make sure the only option that is checked is "Use Raft." Begin printing.

Step 2: Finishing Touches

Once the printer has completed printing, remove the tripper and raft from the print bed. Using a pocket knife or other fine edge, pry the tripper away from the raft. Your tripper is ready to use! Repeat the process for the ON tripper.

4 New OEM Trippers are $12.00 online.

A spool of ABS filament is $22.00 online for approximately 330 meters.

A tripper needs about .8 meters of filament which comes to less that 7 cents per tripper or 4 trippers for less than 28 cents.

    I have one of the digital models, and they are limited to 28 programmable events per day. In some cases, I am setting up 50+ events per day (misting and CO2 cycling). I also have a model that has little flip tabs, but since I have several of the heavy duty dial ones (before a heavy duty flip model was available), I needed a solution for the dial timers I already had that didn't involve spending 20 bucks for new timers.

    I know this is instructibles and we try to fix things or improve things ourselves, but I still think you should upgrade to a digital unit. It would make things much easier (that is it you can afford it yet they have gotten much cheaper over the years). Still great instructible though!
