Tape Dispenser
Description
The openscad file is somewhat parametric but is untested it with any other settings.
It uses syvwlch's awesome thread library ( thingiverse.com/thing:8793 )
So, you'll need that if you want to use the scad file.
Instructions
I have redesigned the plastic blade so that it works pretty well. It doesn't make quite as clean a cut but it seems to work fine (at least from my printer with a .2 layer height).
If you print out the one with the slot for the blade, I've found that it seems to work best if you bend the blade so that it is pointing away from the roll after you stick it in the slot (and glue it).

Printed out the one with the plastic blade in 0.1mm and 0.27mm layers. The 0.1mm cuts fine as printed. The 0.27mm require a little bit of filing on the cutter to sharpen it up. Nice work !
Wow, that's AWESOME!!!
How about making a bigger one for Kapton Tape? That would be useful...
Thanks!
i hate when you dont have a dispenser for tape!! this fixes everything! yeah!
As soon as it was off the printer and without trying it, I took it to my wife to show her that I printed something useful. She immediately tried it and it didn't cut well. While it withstand a beating from our 5 boys, it won't cut so they wouldn't use it. She is a tough critic, but rightfully so.
She helped me redesign the metal blade (taken from a saran wrap box) so that it sits lower. I used a soldering iron to melt the plastic and lower the ledge where the blade goes. Then I melted the blade into the plastic. The key is that the tape has to held still either by your hand, or the plastic ledge preceding the blade. You can also bend the tape down 90degrees before cutting. It may also depend on the tape you are using. We were using removable tape.
Now I have printed something useful! Perhaps I should just stick with that list of things my wife has that she has been asking for.
I agree that the plastic blade isn't great. I think the teeth just aren't quite sharp enough. Mine worked a little better after I scraped the top surface of it with a matte knife to smooth out the top and sharpen them up a bit.
For the one I did with the metal blade (from a wax paper box), I stuck the blade in and bent it over 90 degrees away from the roll so that when you pull the tape out and down across the blade it cuts. That one was acceptable to my 7 year old...
Printed @ 0.2 mm layer height in ABS and it printed very well. I actually use it for small rolls of masking tape and the plastic teeth work nicely. One modification I would like to see on this model would be the addition of some "feet" so that when sitting upright on the table that it doesn't rock around.

I printed this with PLA at 0.36mm layer height. It actually printed quite nicely! The cap screw on and off after a bit of cleanup, even though it's at a low quality. It works relatively good for a printed object. Since I have my HBP working nicely, I'm going to go see how well the blade-insert version works.
Unfortunately, while it's cute, the plastic teeth aren't quite sharp enough to cut the tape easily. I'm printing a new version that has a slot that you can stick a metal blade in (perhaps cut off a wax paper, plastic wrap or foil container).
I'll upload the STL for that soon.
I agree with Pointedstick. Very nice design, and it's completely parametric for different sized tape!
genius! one of the hardest things to do in CAD is to center a circle. You nailed it!
