Herb Dryer (Extremely fast)

This is an herb dryer powered by a fan that I created. My grandma and aunt grow herbs in each of their backyards, but to use them, they have to dry them. this involves hanging the herbs up by string from a hook, or any other method of air drying. This setup utilizes boxes with a hex grid on the top and bottom allowing air to pass through. you can stack up to 10 boxes with 30 different herbs in one tower, however we found it worked best with 3-4. 

Fan unit:

The fan is inserted into the fan unit by pressing the logo side down so that it will suck the air up from the bottom and blow it up into the room.  This design also enables the unit to work as an air freshener, spreading the scent of fresh herbs throughout the surrounding area. This is the fan that I used, but any fan with a 120 mm casing should work.

Magnets and Multicolor labels (OPTIONAL):

Import the “Tags” file into your slicer. the text and main bodies should be separate, but if not, separate to parts and not objects. Paint the text one color and the bodies a different color. The Boxes with magnet holes need to be printed with minimal organic supports. I used simple 2x6mm magnets I found on amazon. You may need to use a clamp to force them in, which is what I did, and it worked fine without glue. there are 9 readymade labels, as well as one blank for you to customize.

Print settings:

You can fit all of the parts on a Prusa MK series bed, or anything larger obviously. I printed all of my parts except for the labels in PETG. I used PLA for the tags. I used 0.2mm layer height on the tags, box with magnets, and fan casing pieces. everything else can be done in 0.35. 10-15% gyroid infill is recommended, but unless you're stacking the units 100 boxes tall, it doesn't really matter. I used a standard 0.4mm nozzle. You will need support on the box with magnets, the stand, and the main lid. You'll need to glue the lid lip onto the groove of the main lid. I did this because otherwise, you would need a lot more support.

Usage: Once you have your herbs, from the grocery store or home grown, simply put them in a box, label it if you want, and put the lid on. Stack as many boxes as you want, but on the top box, put the fan unit on instead of the lid. Place the entire unit right side up on the stand. this is so it can draw air up from the bottom. Turn the fan onto medium or high power (it's still quiet), and let it run for 5-7 days. 

Feel free to gift this to anyone who grows Herbs! No selling. or I will find you and you will wish I hadn't. 

Happy Herb drying!

And printing :)
