animeloverlela these I used 5 minute epoxy. My newest pieces I’m building I changed it a bit. I used super glue and some kicker to initially assemble the pieces. Then I would go back over all the seems and weld them together with a soldiering iron. I have a post with pics in my build thread here Introducing Spitfire Company 3D Printed . This method seems to be much stronger and easier then epoxy. Hope this helps and happy building
