The button that came with my case for the Meshnology Wio Tracker L1 didn't select correctly.  I would press to select and it would move left or right. Was extremely frustrating!  I made this one and it works perfectly for me.  your results may vary on your printer though as it is very small and the hole has to be exact!  I printed it on my Ender3 V2 Neo on standard quality (.2mm)
