I made those stands for Native Instrument Kontrol S2 MK3 as tables are always too low!
STL is plain, it is up to you to “infill” it with your pattern of choice.
With PrusaSlicer, import STL and remove top and botom layer, set Perimeter to 4 for a bit of sturdiness as shown in screenshots.
Choose your infill pattern and adjust infill percentage to obtain desired effect.
This one is made with honeycomb 5%.
C part is a bit different to be able to plug USB cable.
Print part count:
2x A
1x B
1x C
Printed on Prusa MK3S in Prusament PETG Prusa Orange 0.30 DRAFT mode with standard 0.4 nozzle.
