I liked the original cardholder and have a couple printed, but needed solo rows for bigger cards to fit Fantasy Realms Deluxe's box. A quick tinker in Tinkercad and off to the printer. Finishing 2 sets of 3.
Cascadia update: finally got game to the table and extended the cardholder to 220mm to take 3 cards and printed in blue. Printing another 2-card holder in blue too. Uploaded the 220mm card holder here.
The author remixed this model.
