A simple tablet holder for Matrix Ascent / Suspension Cross Trainers with screw holes on the backside of the console (26cm apart on my E3X). Fits tablets with 16cm width (I'm using a cheap Amazon Fire HD 10 tablet). It's not very refined, but does the job. ;-)

Print the model twice, mirror along Y axis for the second print.

I used black PLA filament with a 0.6mm nozzle, PET is probably an even better choice. No supports needed, 15% infill recommended.
