Open source design for 3D printed driftskate/freeskate

Customizer

Added support for OpenSCAD/Thingiverse customizer. Compiling the trucks with a high quality setting (above 10 or so) takes too many resources for the online customizer.

Recommend downloading the SCAD file and compiling locally for now. All parts besides the Deck require setting Quality to 100 for best results. Examples:

If you are making custom trucks and the quality setting is too low, there is a risk the wheels will rub against the truck.
The adapters will have trouble fitting M8 bolts if the quality is set too low.

Any parts generated using the Customizer should probably be run through netfab before printing as well. The truck models in particular require some automated repairs to the STL files for best results.

Design

The skates are made up of three top-level modules that you need to print:

2 Decks
2 Trucks
8 Bearing spacers

Additional parts required for build:

4 M5 bolts
4 M5 nuts
4 M8x80mm partially threaded bolts
4 M8 locking nuts

Note

The bottom of the M8 bolts can just barely strike the ground when the skates are tipped over. This can be avoided by either cutting the bolts short or by adding M8 washers near the head of the bolt. You can probably also use M8x70mm bolts instead of cutting, but that will leave threading underneath the bearing spacers.

The width of the bearing spacers needs to be adjusted to fit your choice of wheels/bearings.

The default design is compatible with JMKRide Performance Wheels/Bearings. Width of the bearing spacers will likely need to be adjusted to fit other wheels.

I do not own any other sets of trucks or decks, so I am assuming this design is not compatible with any existing products on the market. If anyone wants to request specific bolt sizes or hole spacing for compatibility reasons, simply send me the requested dimensions and I can implement them in the next revision.

Disclaimer

I use these skates personally. However, I cannot vouch for the safety or validity of this design. Anyone who chooses to use this design does so at their own risk. The printer/user should perform their own due diligence, materials choice, and testing prior to riding on these skates.

Kudos to Design Prototype Test

I originally printed a pair of skates based on the their video/design. I fooled around with them for about a year before deciding that the wheel size was not to my liking and very difficult to pump. I decided to make my own design that utilized JMK wheels, as the JMK wheel size and profile seem more conducive to learning how to pump the skates.
