I highly suggest printing out the files labeled "Lonk" and "Lonk platform." To ensure a smooth fit, I recommend scaling up the platform by 1-2%. If you choose to print the entire project in one go, you should be able to do so without any issues as long as you print it facing upwards and have good leveling and bed adhesion. This method works particularly well when using e-shop cards for Christmas or birthday gifts.
