This mouse-themed holder will keep your headbands well-organized and on display!
Design features
60mm curve radius should fit standard Disney headbands quite nicely.
Can be wall-mounted with two hidden screws (25mm spacing, #6 countersunk wood screw).
Printing
Print the model as-oriented in the .stl file.
No supports should be needed.
Hidden screw installation
Prepare two screw holes in a vertical line, 25 mm apart
Insert the #6 countersunk wood screws
Gently place the holder over the screws
If it is too loose/tight, remove the holder and adjust the screws
Notes
I've designed this with OpenSCAD in a parameterized way. If you'd like any modifications (e.g., curve radius or arc, screw dimensions/spacing, etc.), please send me a message and I'll see what I can do.
