Hey there, dear colleague!
As you've probably seen from the video, here you'll find all the resources to make a drawer for your A1 Mini, printable right on your A1 Mini.
You'll receive the printing file (for Bambu Slicer and Orca Slicer) along with assembly instructions, plus details on the materials/tools you'll need.
 
Update:
If you're not interested in the poop drawer, following some requests, I've redesigned the left side panels, removing the holes for the drawer guides.
So, if you only want the drawer cabinet, replace the walls in the main file with those from the file LH Side Smooth.3mf.
 
Update 03/04:
Thanks to Johny's feedback, I have made some modifications to the screw holes; indeed, some of them had incorrect diameter and depth.
 
Enjoy the printing process and your brand-new drawer.
Catch you later,
Enrico
