Thanks @guppk for the design, I tweaked it to fit my devices.
Part A - Samsung Active 2 (I stuck a magnetic sticker to the back so the charger can be removed if required)
Part B - Mcdodo wireless charger (https://www.mcdodolife.co.za/products/mcdodo-magsafe-charger)
I'm new to designing so I used Tinkercad. I got the alignment to fit as best as possible and it does.
I used PLA, at an infill of 10%.
You'll notice I included a 10mm hold on Part B, I wanted the charger to fit snug and didn't want to jam a sharp object in the side.
Side Note: I need to fix my Z axis because there are lines that appear on my print. Just haven't had the time so I know
