Working on a 3d printed chassis and I'm thinking through the emitter end of it now... I'm trying to attach heat sink to the inner chassis so that they come out of the saber as one. All the external pieces are MHS V1.
I'm wondering how hot that heatsink gets and if it'll be okay to be indirect contact with printed ABS. Ideally, I would like to replace the silver/aluminum piece with a printed part and then thread the copper piece into the entire assembly. Another option would be something that fits into the channels in the coper - this wouldn't completely hold it in place but it's a start. A third option would be to drill and tap the back of the copper and devise something a mechanical connection to attach it to the printed parts.
Any thoughts or guidance?
BTW, the ABS prints at 230-250 degrees celsius (~450 degrees fahrenheit) and I've used it for a phone mount in my car, so I know it's good for at least 120 degrees fahrenheit (Arizona parking lots).
