This horn is designed as part of a cloak, with the intention that the horn be removable from the cloak to minimize the accidental stabbings when raising or lowering the hood.
The horn itself is printed in vase mode. Then a cheap soldering iron used to melt a hole in the bottom.
The base is printed in two parts, and is designed around the battery/LED light holder (https://www.amazon.com/gp/product/B01J5FY2GI/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) and the magnet (https://www.amazon.com/gp/product/B07CVRPZYY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1)
With the battery/light holder slotted into the top portion of the base, it is very difficult to remove the battery, so a small piece of paper is used to turn the light on and off.
The magnet is attached inside the bottom of the base using a 3d pen to add a thin rim of plastic above the magnet, securely holding it as close to the base of the print as possible.
A small piece of wire is then used to complete the hinge. This was done to allow a little bit of give, making the snap closure of the base easier to open and close. When printed as a single piece with a built in hinge, the base was very difficult to open, and the hinge was less sturdy. This was also all done with the knowledge that the horn is fairly fragile and I wanted each of the pieces to be easily replaceable.
Once the base is assembled,the horn is placed on top (lining up the hole in the bottom with the LED light bulb in the base) and the 3d pen is used to run a bead of plastic around the connection, sealing the two together.
