Heres a video of it skating: https://streamable.com/5im9a
The skateboard is printed in 3 parts and can be comfortably printed on any platform 22 x 22 mm or bigger. Running through the skateboard are two 350 mm long pipes of 18 mm diameter that act as reinforcements. The bottom has an area for a laser cut insert simply because it looks cool. This piece can also be handmade and any material can be used.
I originally planned to make the wooden laser cut piece out of frosted acrylic with my schools laser cutter. That didn't really work though because after cutting it i realized the engraving was lighter than i thought it would be and didn't really show well. Instead I just used some piece of wood I found in my school. I found the pipes laying around in my basement which I cut to size. For the actual print I used my ultimaker 2+ and printed it in 3 parts.
Because I decided to switch from an acrylic bottom plate to wood, the recess i made in my model was not thick enough. This is why i modeled the spacer piece which goes on the back two screws to keep that truck level with the other one. If you decide to make this, just rescale that piece so that it's level with your material.
You can probably buy all this at your local hardware store for a lot cheaper, i bought most of it at ace. But, here are amazon links.
