This is a real working tape Dispenser. i made it in Onshape, and if the hole is too big for your tape roll you can edit it here:   tape dispenser. | Part Studio 1 (onshape.com) you can also edit “Shell 1” if it's too flimsy. it also has actual spikes on the end for cutting tape! 

well thanks for checking out my design! hope you have a great day! :)
