Gridfinity Tape Dispenser

Here is some gridfinity storage for standard 19x60mm tape rolls with a 25mm-ish (1") center hole. Scotch tape or equivalent. You know the ones.  

Worn out hack-saw blades will frequently have some still usable teeth near the ends so there is a slot to recycle a piece of blade to cut the tape but feel free to adjust the slot to fit the cutty-thing of your choosing. 

If you'd like to attempt one handed operation some supplemental gravity may be required. There is 20x20x4mm holes in the bottom to hold weights. will that be enough? probably no. good luck.
