Inspired by wooden planters sold at big box stores, as well as wanting a cohesive look for my garden and more space on my balcony, I made these repurposed pallet wood planters to hang over my balcony railing.

List of Components:

• Pallets 
  • I used 2 to make (5) 23" long planters
    • I was worried about strength and chose to make shorter planters, but having used these planters for ~1 month, they could probably be up to twice as long and still hold up well
• (12) 1" screws and (8) 1¼" or 1½" screws per planter
  • I ended up using 16 total screws which seemed sufficiently solid, but the design can hold up to 20 screws 
• (2) 1" metal corner braces per planter 
  • Adds extra strength for each hanger, but still very strong without it
• Mitre saw
• Short stubby screwdriver, or 
• Long screwdriver
• 2x Hangers and 2x Brackets (R & L)
• Some method of sealing the wood 
  • Or don't seal it, up to personal preference

Printing Instructions (Hanger/Bracket):

• 4 walls, 15% triangle infill 
• Hanger
  • PETG
  • Add a pause to insert the 1" corner brace
  • Paint On Supports 
    • Do NOT auto generate supports because it will create supports in the corner brace void and won't allow you to insert the metal brace
• Brackets
  • PLA+ or PETG
  • Also needs supports, auto generate OK

The Process:

1. I hosed off the pallets and let them dry as they were rather dirty.
2. Then I took the pallets apart for the long top and bottom deckboards, taking care not to damage the boards too much when removing the nails.
   1. Keep track of your nails! You don't want to accidentally puncture a tire.
3. The boards were cut into 23" lengths using a mitre saw. Damaged parts of boards were also cut off.

4. Rather than stain the wood, I decided to use the Shou Sugi Ban method of preserving wood as I much prefer the look.

   2. As I have just a small torch, I burned only the portions of wood that will be visible when the planter is fully assembled. If you are concerned with longevity, the best practice would be to burn all 6 sides of the boards and seal with oil.

      The difference between unburned, burned, and brushed to expose the wood grain.

       

5. After brushing the black char off, I elected not to rinse the boards of soot since I wasn't going to oil them either.
6. I slotted the boards into the 2x Brackets (R & L) and carefully screwed everything together.
   1. Drill was used to make pilot holes as necessary.
7. The 2x Hangers were attached and also screwed on.
