This model is aimed to make a person's life more comfortable which can range from severely reducing foot pain to quenching a small itch on the foot with a much needed scratch. The foot is a difficult place to reach with our own hands and comfortably massage it. This model allows for an easy and comfy way to massage feet while doing another task with the hand and the mind, for example, working at a desk while needing to scratch your foot.
The model requires very little support. I printed this in 6 separate prints on the Bambu Lab P1S with a 0.4mm nozzle, Bambu Lab PLA Basic White and supports on. I also used 608zz ball bearings and M3 * 15mm screws.
If you decide to print this model with the updated files for the roller which make it stronger ( this includes files: [Spikey roller (7.5mm) with hole] and [Axle]), please print the axle file on its side. This means the major force acting will be perpendicular to the layer lines for maximum strength. The tolerance for the hole on the roller to fit the axle is 0.14 mm (this worked well on my printer). If this is too small and you are unsure how to amend for your printer, please add a comment consisting of the tolerance that will work and I will be happen to amend the file.
