Star Trek Com Badge Coat Hooks and Door-Knobs

Coat hooks featuring a Star Trek communicator badge. The hooks are designed to be mounted to a wall and are perfect for hanging coats, hats, or anything else you can think of.

Design

The back of the hook is hollowed out to account for uneven walls or dowels wich are not completely flush. This requires supports, but as they are attached to an invisible part of the hook, they don't influence the final appearance at all.

Colors

As you can see, introducing a filament change at the right layer provides for a very nice visual effect.

Knob

If you change the parameter type to knob you can print a knob instead of a hook. This is useful if you want to use the badge as a drawer knob or something similar. I haven't printed this version yet though.

Instructions

I printed the hooks with 50% cubic infill and used PLA as a material. One of the hooks gave in to the wait of two heavy jackets and a pair of quite heavy jeans. I then reprinted it with 90% cubic infill and cranked up the nozzle temperature to 240°C for the first and 230°C for subsequent layers.

I also changed the cooling options in PrusaSlicer to improve layer adhesion:

Fan speed min: 50%

Enable dynamic fan speeds: true

speed for 0% overlap (bridge): 50%

speed for 25% overlap: 70%

speed for 50% overlap: 80%

speed for 75% overlap: 100%

Adding more perimters would have made the hook even more sturdy I think, but mine has held up for a few weeks now with no issues, so I had no reason to reprint it.

Also it was only one hook which failed so far, the others are fine, even with the lower infill and cooling settings.

Organic supports work great on this one.
