In April, I uploaded an earlier version of the Soul Extractor, which gained popularity among many. However, I found that due to variations in printers and materials, a few users encountered difficulties in assembling the massage claws. I have now re-optimized the model, no longer using an interference fit to secure the massage claws, but instead, a small fixing part is used for attachment. Additionally, I designed a not too loud ‘bell’ at the end of the handle to attract the attention of pets. You can put the small cube included in the print file into the bell to make it sound.

One issue that remains unresolved is the adhesion of the massage claws to the hotbed. As the claws need a certain degree of elasticity and cannot be made too thick. Moreover, as the claws come into contact with the skin, the use of brim is not feasible to avoid sharp edges at the brim connections that could scratch the skin. Try to use solid glue or spray to increase the adhesion between the massage claws and the hotbed. At this stage, I can only provide models of individual massage claws (with options of 12, 6, or 2 claws). You can print the required number of claws to ‘solve’ this issue, as the Soul Extractor requires 10 claws.

The Soul Extractor effectively targets the scalp for massage, delivering a wonderful sensation of comfort. You can use it on your furry companions and observe their amusing reactions. It’s important to note that the Soul Extractor should not be used if you or your furry companions have injured skin or specific health conditions, to avoid causing discomfort or harm.
