A1 Mini - Rear Gridfinity Baseplate with Magnets

The previous model didn't have spaces for magnets, which I find are necessary for such a precarious place on the printer.  
Another issue was the strength of the part. I've made my version thicker.  
I also had to completely recreate the design since the original author didn't provide STEP files.  

The Print profile I've added has 2 plates. The first one is an orientation which provide much more strength but will unfortunately require more supports. The second plate is a more standard orientation with minimal supports.  

I've printed in both PLA and PETG successfully.  
The model relies on the adapter / mounting plate used normally for the spool.  
If you need an extra plate like I did, I printed another one using this model:
