Arboreal feeding ledge
thingiverse
This is a simple arboreal feeding ledge to fit self printed cup, as well as "jelly pot" cup. Use 20x5 magnets to hold on glass (i tested with magnets on ledge side and 20x20x3mm steel washers on outside and hold is ok in 4mm glass) Back side there is 3 holes for silicone buttons to give more grip to the terrarium wall (8x3mm) Can also use just piece of duct tape.
