Toilet paper holder extender + quick change

thingiverse

This thing allows your toilet paper holder to hold larger rolls, and also provides the ability to quickly change a roll. Just lift the roll in from the bottom then rest it on the bars. When it's empty, lift it up to remove it. I had poor results with auto-generated supports, so I created a version with included supports that worked well for me. You can use that if you like or create your own supports. Either way print two copies of that part along with two copies of the bar. To attach the bar, take a straight piece of 1.75mm filament. Heat up a piece of metal (I heated a putty knife with my heat gun) and press it to one end of the filament until it widens and flattens to your liking. Put the other end through the holder and bar, then snip off the excess, leaving a couple of millimeters, and then flatten that end, too. Be sure to insert the bars in opposite directions or they won't work together. The curvy shape serves as a spring to make it hold tightly to the existing holder. I used PLA, which is very stiff and held very tightly, but was difficult to put in place. More flexible filament might work better, but with the risk of not holding as tight. If anyone uses a different material, please leave a comment to let us know how well it worked. Update: I made a [better version](https://www.thingiverse.com/thing:3565889) of this that uses flexible filament.
