No-Sweat Shoulder Pads

Introducing No-Sweat! Camping and Hiking on hot summer days can make us all sweat and it's made even worse when our backpack straps collect that sweat and become drenched. Not only does the sweaty fabric prevent heat dissipation and cause even more sweat but it also softens your skin over time, which can leave it tender or even rug burned. Straps can also cut into your shoulder over time, which is also prevented. These shoulder pads are designed to separate the stagnant, non-breathing strap from the surface of your shoulders to allow air flow and sweat to evaporate underneath the strap, keeping your strap dry and shoulders cool. The grooved portion on the top retains straps that want to slide off. I intend to make a version that goes between the backpack and the back so stay tuned!

PowerMeshNoSweet features the use of fabrics in 3D printing. You can buy Power Mesh on amazon (90% polyester and 10% spandex) and you will need enough for 2 pieces the size of your build plate plus. The filament in this case is your choice but I'd avoid PETG due to adhesion limitations (you don't want to use a brim for this one). PLA and TPU are probably your best options. When you load this model you'll want to load it as multiple parts and set pauses at the heights where the fabric models are prior to deleting the fabric models (the large flat, thin sheets in the drawing). SLICE AND PRINT AT 0.24 LAYER HEIGHT and place the fabric down on the build during the pauses.

TPUNoSweat This one is fun - The whole print is one piece and flexible BUT you'll probably need to have your retraction PERFECT for this one unless you want a cobweb - i guess even if you get a cobweb you can burn them with some flame. It does have some bridging to make the mesh that holds the pieces together. This should be a harder TPU like 95A. I don't think the soft stuff will work as intended.

This is intended to be worn over clothing otherwise you may get pinched.
