These work great. They push down nice and snug and prevent the sticks from moving much at all! Thanks. Printed on Duplicator i3 with Hatchbox TPU. 40% fill. I'm going to print another with full fill to see if they move even less. But really not needed. They slide on nice and do the trick! Here's a vid also so can see the minimal travel. https://youtu.be/RUSPmd9TDKc The also don't touch the screen as someone asked. It bothered me every time I slid the controller in the case that came with it. I worried about the sticks with the snug fit of the case. Thanks again!
