Please note! 

Xbox one and series controllers use slightly different battery covers
Please make sure to choose the right one! Using the wrong one can end up with the tabs breaking in your controller (which shouldn't be dangerous but will surely be annoying).

Update 29.10.2025

Merged both versions (One and Series) under the same post for better discoverability.

Description

I had printed and used the original mount and then got this idea when I saw a printable battery cover for the controller. I just pretty much just mashed the two models together and got this as a result (had to add some structural support though). It's very hard to believe but it's actually more sturdy than the original mount, try it and be surprised!

Parts list

1x Mount Phone Clamp A v6
1x Mount Phone Clamp B with Tab v6
1x Mount Phone Clamp Bolt v1
1x Mount Phone Clamp Knob
1x Knob_v5
1x Bolt M5x25 v1
1x M5_Nut
1x The printed battery cover from here

Instructions

Should be printed laying on its side with supports. Raft or brim may be needed if your bed adhesion isn't stellar.

I highly recommend using metal nuts and bolts in place of the printed ones! I couldn't source a M5x65 bolt myself so I made one from threaded rod (just glued a nut to one end)

You also might need to print the Hex Shaft which is used to tighten the phone clamp knob's cover in place.

I uploaded the needed parts here but you could also make a custom config if need be!
Also supplied the .f3d and .step files of the cover for easy modifying!
