This instructable will walk you through creating custom skates made just for you! Through the magic of 3D printing you can make ones shaped perfectly for your feet. Not only that, but they are lighter than normal rollerblades (The pair of printed skates is lighter than my one normal skate which weighs 3lbs) and also more portable. They can be clipped with a carabiner to a backpack and with a quick lacing method using 'S' hooks they can be put on or taken off in 30 seconds. In the video I am riding one printed rollerblade and one regular, this is because I hadn't printed a second one yet but it gives a nice side by side comparison. The printed rollerblade was surprisingly strong, I didn't have to 'baby' it while skating and I ride on one leg a couple times in the video to show how stable it is.
I'd also like to address some common concerns: I went with a 3 wheel design because I wanted the bottom part that held the wheels to be a single, solid piece and a piece for three wheels was the largest I could print on a Makerbot Replicator 2. As for comfort I used some craft foam and packing foam in the boot and on the footplate and between it and my normal skate I couldn't tell a difference. I didn't include a 'brake' on the skate because of size constraints (a separate piece could definitely be added) and I've never used them as I feel toe dragging is a better stopping method.
To make this project you will need access to a 3D printer, or a company like Shapeways, as well as some general CAD knowledge for the program you will use (the tutorials they offer should be plenty). For these instructions I am using Autodesk Inventor 2013. Also make sure to wear the appropriate safety gear and use caution when testing! Most importantly, have fun and be creative! Updates:
Since building I have made a seconds skate and found that the toe part of the boot and the tongue are essentially only for looks so I updated my design without those and just added a little toe guard to the end of the boot for safety. All the files will still be on the thingiverse page.
The files for all parts can be found on Thingiverse HERE
