Holy Carp we’ve come a LONG WAY!
I wanted a phone mount for the motorcycle, I just didn’t want to spend $150 for it. $50 RAM mount, and a few minutes in Fusion 360, telling it I needed an M10x1.25 thread and the Prusa MK2 printed it…the thread is PERFECT.
I’m trying to decide if ABS+Locktite is all I need for retention, or if I need to design in an expanding camp for retention.
The power of 3D printing really does come into fruition once you’ve learned how to model and start seeing the places where it can be used and applied appropriately. Congrats on getting this far, lots never make it to this point. This is where it becomes an actual career. 
Just learn each other
Just be careful, Loctite and plastic do not play together well.
@Bud_Hammerton good to know. I’ll most likely play with friction fit or design in a wedge
@Mike_Miller @Bud_Hammerton Loctite (Henkel) makes a specific formulation for holding plastics to metals. I’ll find a bottle we have at the shop and get you a part number.
Most likely you don’t need it to hold the metal stud of the ball into the plastic but more to hold the plastic into what looks like the triple-tree on your bike. For that I would suggest a light wrap with a thin rubber sheet. Should hold well if you can squeeze it in there!
@Mike_Dobrick good to know. The general Loctite that you find in most home improvement centers does react with many plastics.
@Mike_Dobrick Since “Detail is free”, I was pondering a design where a Second allen bolt could create a positive lock in the bore…still thinking about designs. The first one was surprisingly successful with very little effort.
@Mike_Miller I would think a 2-piece design that crushes a soft puck of rubber between the two pieces would work well also. As the rubber compresses it would force itself outward and lodge into the hole nicely.
They used this style of compressed rubber as a stopper for freeze plugs on older V8 engines for a long time.
