When using a toothpaste-squeezer you could always use a third hand ... or this tiltable toothbrush-holder!
I've created this after my girls where complaining how they have to place the toothbrush somewhere before they could squeeze the toothpaste on the brush. I think it serves it's purpose quite good.
I've designed holders for one, two, three and four brushes, each with brackets for mounting it with screws and without brackets, which you could mount on tiles with double-sided tape ... or simply placing on a shelf.
Unfortunately I only had one model of toothbrush so I could only make this specific holder, but as soon as I get my hands on other models I will make holder-inserts for those brushes, too.
The holes in the base are a little wider than the axle, except the right one. This one should hold the axle tight without using any glue. Just stick it all the way through and you're good to go.
I printed the whole kaboodle in 0.2mm with an infill of 10%. Should you deside to use a screw an nut instead of the printed axle I recommend to print everything with 100% infill for stabilty reasons if you want to thighten it.
