Here is MagSafe charger crystal, This amazing crystal will power up your phone in no time, No supports needed, Print in Place. Simply print the model, then line the hole with a small amount of blue tac then insert your MagSafe charger or similar charger, then use the cable channel to run the cable behind the crystal, and place a small amount of blue tac underneath the crystal to hold the cable in place, I used PLA and found the Blue Tac surprisingly strong, if you have troubles getting the blue tac to stick I recommend double sided tape. Print settings, Nozzle size 0.4mm, Layer height 0.2mm, No supports, Print speed 60ms, infill pattern Grid, Infill density 15%
