I've reinforced a little the amazing model by With_Maltodextrin by adding, directly in PrusaSlicer, a pair of solid boxes next to the thinner cylinder. I have kept the in-built supports.
The hole in my eBOX is a slotted hole of about 5x11 mm, if yours is slightly different, you can modify it directly in PrusaSlicer.
The author remixed this model.
