AMS Lite Top Mount Screw Latch Modification

I installed the AMS Lite Top Mount onto my A1, and like many others, felt the latch was less than confidence inspiring. I noticed the standard print profile created an extra screw, so put the pieces into tinkercad and copied the existing internal threads from the upper half into the lowerhalf and made a hole in the latch for that extra screw, adding a small peace of mind assurance that the latch will hold. Probably not necessary, but if it's something you would want, here it is. :)

 

While I was installing these modified pieces, the original extra printed screw broke. Bambu has a negative part added to the original printed screws to force them to be hollow. I removed that hollow, and reprinted the screw at .20 strong, with 5 walls. I also added some flats to improve the horizontal printing that results in a significantly increase strength. I added two to the latch mount plate and have the .stl file in downloads too incase you also want to print an unreasonably strong screw for a probably unnecessarily reinforced connection.

 

Simply print these new pieces, and use the existing metal hardware screws to attach the new lower half to the new latch together, snap onto your top bar in place of the original pieces, and use the printed screw to ensure the latch doesn't come open on it's own, even though it probably wouldn't happen anyway, but now you're maybe more sure it won't.

 

Enjoy.

 

UPDATE: 25/02/12- Re-uploaded the .3mf file with improved supports, added strength, and added two improved screws to the plate.

 

UPDATE: 26/06/10- Re-uploaded a revised .3mf that better fits the A1 Mini plate and has higher resolution to reduce triangle resolution artifacts
