This is a phone stand that fits the £5 IKEA LIVBOJ wireless charger.
Depending on your model of phone and the location of the charging coil, you may need to tweak the model. The raw Fusion file is attached (it appears under “Download STL”) and you can click Modify → Change Parameters to change the dimensions.
If you modify the profile, please consider uploading a print profile named with the phone model (and if appropriate, case thickness) for others to use! You can open the default print profile then right-click the model and choose “Replace with STL" to replace the model but keep the same settings (including increased infil for the base for some extra weight).
