Intended to fit the GRS button hole spinner set. https://thunderstickstudio.com/collections/spinners/products/usb-spinner
Only 150x90x45mm size so should fit any 3d printer.
Uses four M4x12 countersunk screws to secure the bottom cover.
The bolt holes are sized to be self tapping.
I used the foam insert from the box it came in as a grip for the bottom.
Fusion360 archive and step files included.
