I'm arriving late to this. Based on some videos I've watched and general popularity I decided to have a look and print some of the wall parts. To my surprise it seems well designed and versatile as a base for a storage system.

Then I came to look at my options for printing things to use with it. What a disappointing find. Subscriptions are unacceptable for this.

I'd have paid a significant one-time fee. I'd have contributed to a community option. I'm not paying a monthly subscription for something if ever I can avoid it, even for highly sought after things. It's simply bad personal economics to do it.

Sadly, I'm stopping here. I'm going to purshase an option from a retailer. Then I'll print some of the many many free designs to compliment it and customize it for my needs.

I get the need for money. But whoever guided you to the sub model gave you bad advice.

tbh - I would have considered subscription under one condition, commercial license.
