Update April 2018:
After seeing all the remixes of my design I thought id take into consideration some of them and have a redesign.
Thickened up the rear support
Added a support to the base
Added logo to each item
If you find something not quite right feel free to improve the design
V3 still available for the remixes

Update:
Design changed to add additional room for charging cable which has been requested by a few people.
Version 2.3 is still available

Stackable Xbox One Controller Stand
Additional holders can be printed and slotted in on top of each other

This was based on the wall mounted holder by Hegmar

Hopefully this has been resolved
