In this instructable I'll show you how I solved a problem that I had with my pennyboard.
When I cannot use my pennyboard (inside the university for example) I used to keep it in my hand or, when I needed both hands, between my backpack and my back. (picture#1)
That is not a good place. First of all because since the pennyboard deck leans against my back, I finish always to get a dirty t-shirt, and second because in that way I often knock into something or someone.
So I decided to create two attachments on the backpack that afford me to keep my pennyboard vertically. Follow my instructable to understand how to realize it in less than 15 minutes with a total cost of 2$.
Step 1: Materials & Tools
- 30cm of nylon strap
- 25cm of bungee cord
- 1/2" brass grommets (2$ for 25 pieces and the punch)
- 1/2" hole puncher
(or a small metal tube)
Step 2: Mark the Places for the Holes
First of all you have to mark the places where you will make the holes for the attachments.
In order to be more precise, I suggest to put the pennyboard on your backpack as in photos.
You have to mark two little dots (per attachment) about 2cm from the board.
These are my measures: 15cm for the bottom attachment, and 18cm for the upper one.
Step 3: Cut the Nylon Strap and the Bungee Cord
Now we need to cut the nylon strap and the bungee cord to the right lenght. I bet that you can find them in your house.
The bottom attachment will be used to insert the board in, so it needs to be the sturdier. I took a piece of nylon strap and I cut it oversize, with a surplus of 5,5cm per side.
In this way I can fold 4cm on each side (photo#1), making the attachment a little stronger.
The upper attachment instead needs to be more flexible, for removing and inserting the board. I took a bungee cord, and I cut it leaving also here about 4cm per side for the knots.
Once you cut both pieces, I suggest to reinforce them by burning quickly all the ends with a lighter as you can see in pictures#2,3,5.
Step 4: DIY a Hole Puncher
If you don't have a hole puncher and you don't want to waste money buying it like me, here it is how to make one.
It's really quick and simple. You just need a scrap piece of tube with the same diameter of your desired hole.
All you need to do is to file one end with an angle as in these photos. Once you see that is become sharp, you can start to use it.
Step 5: Make the Holes in the Nylon Strap
We need to make two holes on the nylon strap 15cm apart (measure taken in Step 2).
Place the nylon strap on a hard surface (I used a scrap piece of metal) and make the holes.
You can make them by hammering the hole puncher, or even simply by pushing and rotating it clockwise and counterclockwise. (photo#2)
As before, I suggest to burn quickly the holes with a lighter in order to make them sturdier.
Finally repeat the process with two small pieces of nylon strap of 4cm x 4cm that will be used to reinforce the upper attachment.
Step 6: Make the Holes in the Backpack
As in the previous step, put the scrap piece of metal inside the backpack, push and rotate the hole puncher at the same time to make the holes, and finally reinforce them with a lighter.
Step 7: 1/2" Brass Grommets. How They Work?
Usually half inch brass grommets are sold with a metal base, and punch (a metal rod with a convex tip).
This is how they work:
- start by putting the "bigger eyelet" (the one with a long neck) on the metal base
- insert it in the nylon strap, the bag, and finally the other eyelet. (it looks like a washer)
- insert the punch on the top
- finally hammer the punch
Step 8: The Upper Attachment
Following the previous step, fix two brass grommets on the previously made holes.
Remember to insert the 4cm x 4cm nylon strap pieces that we prepared before, to reinforce the upper attachment
Step 9: Insert the Bungee Cord
Now insert the bungee cord (I quickly spray painted it black) and make two knots per side.
In order to get the right fit I made the first knot, I put the pennyboard onto the backpack, and finally I made the other knot.
I cut the extra bungee cord, and I repeated the burning-reinforcing method.
Step 10: The Bottom Attachment
In order to make the bottom attachment, fix the nylon strap with the same process.
Step 11: Finish! Enjoy Your DIY Pennyboard Backpack
And you have finished!! Taking the pennyboard with me was quite a problem.. Now it's a pleasure.
As I said before, this is a very quick and easy project that anyone can make in less than 15 minutes.
I hope that you find helpful this instructable!
