A small penny board with 41.275mm x 64mm holes. The board is fortified by 8mm x 370 mm rods. The rods I used are scratched rods from one of my printers. The fit is very tight, so I used a hammer to get them in.
Fusion 360 file added if you want to modify it.
The example is printed in Fillamentum CPE. You can use a similar material (PETG). I mainly used this one for a bit of flexibility and impact resistance.
The author marked this model as their own original creation.
