I would start with a warning: If you print this, your house will be full of rubber bands, in corners and under furniture. I found out that my cat loves to chew on rubber bands and it's definitely not good for her to swallow any. So be cautious for the safety of your pets.

As for printing:

This will test your calibration, it's just small enough to fit on a 220x220 mm bed.

Wall line count 3 is the minimum.

The layer adhesion is really important for the mag, if you have trouble, print that part slower.

Otherwise It should be fool proof, if something comes up just write!

Note that the two sticks in the front was changed to a single plate, threat it as the two sticks.

Now you have to find the right rubber bands, if they are too big it will not work properly. I found mine in a regular dollar store.

Finally I want to say thank you for your support and feedbacks. I have to stop refining this model for now due to lack of time and money. I will continue as soon as I can, maybe full auto is coming. Thanks again! Have fun!
