Recently I embarked on an ambitious project, and since I've documented my whole car build on this forum, I thought I'd share this project with you.
A couple of years ago, I created the rennch™ brand as a DIY tips and gear for vintage Porsche nerds like me, but I'd only created tutorial videos...not a real thing.
I was invited to display my car at the Michelin booth at Rennsport Reunion VI, so I thought I should try to come up with something to display for the (So I thought) 6000 people that would attend. (I was only 76,000 people off.)
One of the biggest challenges I have when I do a track day, an autocross day, or a targa rally, is having everything I need to swap my wheels out (change a tire, put your race wheels on, get the car on a jack stand, etc...) and figure out what it's going to do in the car. I have the blue Harbor Freight jack, as many others do, but you can get fancier jacks that have the same form factor as well.
One week before Rennsport, I decided to make a bag that would house and organize everything I needed to change a wheel on the road. I had a couple of requirements.
1. It should look "period correct"
2. It should be well built...like a Porsche.
3. It should be contain everything I need, so at a glance I can tell if something's missing.
4. It should be "mass produceable".
This bag was going to be Prototype v.1.0, and hopefully with refinement, turn into something I can sell under the rennch moniker.
Now...I've never made a bag before. I didn't know the first thing. But...I knew how to cut cardboard, so that's where I started. I made a cardboard mockup, then a template from that mockup:
Then I made a couple pretty crude drawings, and found a guy who does this for a living on fiverr.com to make up some mockups, and when refined, some technical drawings I could send to a factory to have the bag produced.
I knew I was going to call it "jack in the bag™", so I bought some fabric and had it embroidered at a local embroidery place so I could cut and glue the fabric into "labels".
