Once the tubes arrived I made some 3D printed end caps. Using Black high quality PLA. If you have a 3D printer you can download the STL files. (Not for commercial use). You may only use the STL file to make your own set.
The 3D printed end caps were “okay” but took ages to print and the look wasn’t really perfect for the application. So the next challenge was to find some Perspex to cut down. Cutting a perfect disc wasn’t going to be easy with limited tools, however I found some companies that offer cut to size services. The issue is, it’s not a great time to order Perspex due to Covid19 as it’s a main material used for shop counter shields, so demand is high.
So over to Plasticsheets.com to order the discs. You can order what you like on the site and here is the direct link to the custom ordering page.
All the discs we have ordered are Black Acrylic rather than Perspex.
So what did we order for 2 giant cells?
2x 150 x 10mm discs to form the base end caps
2x 150 x 10mm discs with 5mm centre hole for part 1 of the top
2x 153mm x 5mm discs with 5mm centre hole for part 2 of the tops.
The holes in the top discs will allow them to be held together with the positive terminal that we will 3D print and paint silver later.
We took the tubes to a local sign shop, we gave them a Duracell battery to match the colours and fonts. This is the result below.
Our Giant Frunk Batteries nearly complete.
We have also designed some 3D printed stands to stop them rolling around.
The plan is to insert magnets in the stands and a metal band inside the “batteries” to hold them in place.
We are also looking at getting some hard foam cut for the inside to hold the cars emergency kit.
Some come back soon for more updates and images of the finished giant Duracell battery project.
