Key for Paper Towel Dispensers

prusaprinters

<p>3D-print against proprietary solutions</p> <p>We share the restrooms in our hackerspace with other tenants on the same floor. Once a week the cleaning staff does their thing (except refilling the soap, but that's another story), including refilling the paper towel dispensers.</p> <p>Recently the paper towels started to show up in their packaging on the sink. That led to a lot of waste: towels being strewn around, on the floor, in the sink (clogging the drain) and so on. We were not sure what caused this, but - as good hackers - we tried to make things right by putting the paper towels in the dispenser. Well - not so much.</p> <p>The (unbranded) boxes are locked with a weird 'key' - maybe also the reason why the cleaning staff can't refill them any more (lost the last key?). Anyway - we set about to fix this armed with nothing but paper, pencil and a caliper. The result can be seen in the pictures below - colourful keys for the men's, women's and handicapped restroom. (Yeah OK: We also used FreeCAD, our Ultimaker2 and indirectly also approximately 100 global supply chains - but who doesn't.)</p> <p>We left a key in each dispenser and voila - the caretakers understood the (as helpful intended) hint. Now the paper towels are refilled in the proper place again. :-)</p> <h3>Print instructions</h3><p>100 % infill recommended; support for upper end wingtips recommended.</p>
