Currently, it is only compatible with A1 mini. If you want to use it on A1, I will release a new version

If you're using a roll of cardboard on the A1 or A1 mini, you might need this.

When I first got my A1 mini, my printing kept failing because the cardboard roll got stuck in the printer's holder. After searching around, I found some models, but they were too large and too long to print, so I decided to create one myself: very thin, so you won't waste materials and time.

It's very easy to assemble. All you need to do is to put both parts through the filament roll. Due to a 0.6mm tolerance between the two parts, they will be tightly joined together. The entire printing process only takes 50 minutes.

I used eSun PLA+ to print with the following settings: a single-layer outer wall and a 10% infill.

Please give it a try and let me know what you think about it!
