I haven't used this yet but it's better then cardboard. my one thing I wish it had a groove on the backside to put the tip of the filament in. I sound like those Amazon review that say I like it but haven't used it yet with a 5/5 rating.
Hi, no problem that you only give a 3 star rating, the important thing is that you give me your honest opinion and suggest improvements. I created the 1:1 model of the cardboard roll from Bambulab. It has a hole where you put the filament in, just like the original one. You are welcome to watch the YouTube video of how it works. Greetings Ceppeto
