One Touch Rip

Updated SUN  23 JUL 2023I gave the second version to my mother-in-law for beta testing this morning.I ordered some suction cups (they come tomorrow). and updated the base to have six mounting holes for the suction cups – those designs are in the “experimental” folder and (obviously) haven't been tested yet.Updated TUE 18 JUL 2023New arm flexes better and clips to base better.Base has some fillets – otherwise the same.Original in “version 1” folders.SummaryThe objective is to create a paper towel holder that you can use with one hand.The inspiration is Oxo's design, except that I've had three of this break on me (including one that I gifted to my mother-in-law!).And, for simplicity, I want to use a compliant mechanism.And…it has to fit on a mini.What to PrintYou need 1 base and 1 arm.There are two versions of the base – hollow and solid.  I only printed the hollow – it prints 40% faster than the solid.Note: the bases are oriented upside down for printingAssemblyIt should be obvious how the arm connects to the base – there's only 1 way to do it.It's a little hard to figure out how to get the pieces together (it took me about a minute, and I designed the thing), but I don't think instructions will make it easier.UseFor one-handed use, the arm currently exerts too much pressure for the weight of the base.  The Oxo weighs about two 1.2 pounds, and this one comes out to about 25% of that.  So, it probably needs to be weighted or secured to work properly with only one hand.The solid base is probably better if you want to secure it to a horizontal surface.
