Some very difficult assembly required (vex 3d printed controller paddles)

My current models of the 3d printed vex controller paddles printed in PLA are VERY DIFFICULT to assemble, involving lots of use of a jet lighter to attempt to bond the layers of the 3d print together to make it stronger, and around a %50 chance of one of the parts breaking beyond repair. I’ve yet to print them in ABS, which may help, but nevertheless, kits will be delayed for at least 2 more weeks.

Um, could you explain the issue in layman’s terms? I’ve printed out a set but haven’t had a chance to test it yet

How do you print out a set? Do you have a link to the STEP file or something?
