This is a calibration print to test your slicer settings when building the Box Turtle Automated Filament Changer and doubles as a cool fidget toy when you're done!
Box Turtle is exactly what it appears to be. An open source AMS-style filament changer for Klipper machines. Box Turtle uses the AFC-Klipper add-on found Here. The goal of Box Turtle is to deliver a user experience as close to an AMS as possible in vanilla Klipper. i.e. an "AMS" for any klipperized printer regardless of form factor but VORON Design printers in particular.
Note: All parts are pre-oriented and support is already added where needed.

Things to test
Make sure you can easily remove the rear and front supports on the body as well as the supports on the turtle_box_retainer
Remove the rear rubber bumper from the ECAS connection and verify you can push it in with a tight fit.
Test the fit of the MR148ZZ bearing. It should push in with a tight fit.
Test magnet fit in body and trigger. Make sure to install them so the trigger is attracted to the body. We want the magnet to hold the trigger closed. If they are a little loose use some super glue to hold them in place.
Test fit the zip tie in the rear point. These are used to retain the motor wires inside the Re-Spooler so it is important to have zip ties that fit.
Test the fit of the bowden tube in the top of the trigger. Should be a snug fit and not fall out.
Assembly
Screw an M3x8mm SHCS on each side of the trigger leaving about 3.5mm of space between the trigger and the screw head.
Drop the trigger into the top groves on the body.
Insert the two upper tabs of the turtle box into the body then press down to snap it in.
Slide the turtle_box_retainer in from the side to lock it all into place.
Check that you have a smooth movement of the trigger and it snaps shut when it's released.
