Modular Robot Vacuum Ramp

prusaprinters

Getting tired of not having your robot vacuum reaching into rooms because of the threshold? As was I!I made this model as a modular ramp with about 10 degree angle so that my robot vacuum wouldn't stop and think it reached a cliff (a.K.a “The stairs”) when it was crossing the threshold into my bedrom. The model includes endpieces that are rounded as well as straight forward ones (pick your poison), and the modular pieces locks into place with dovetails that should be tight enough to keep the pieces together, but loose enough to fit into each other. The model is made so it can vary height and depth by just changing the STL in the slicer. To keep the angle of the ramp when scaling it for your threshold, keep height of the ramp at 18.5% of the depth.Example: If your threshold is 20mm high, divide 20mm / 0.185 to find 108.1mm of depth. You can also edit height / depth using the percentage option in i.e Prusaslicer to acheive the same thing.Use some double sided tape to fasten to the floor. Hot tip: If you go for the version with straight ends (rather than the curved), flip the model on its head to acceive a nicer finish.  Edit: After publishing this model, I see that @Dr.Peter already made one very alike this one. I wasn't aware that he had made one when I made mine,  which I guess goes to prove that “great minds think alike” or something like that. If my design does not cut it for you, go check out his design to see if it tickles your fancy :-)No supports0.2mm layer height30% infill (suggestion) Please leave a like/heart - You never now if it is my self esteem or ego that will get a boost *Shrug*!
