Guide for making Core version 1

I did a few layers, then placed the nubs in. It helps to poke the allen key through the bottom of the mold and through the weave, then chase it with the bolt. tighten the nubs securely into place, continue applying layers then bag it.

If you have access to a vacuum pump, you can use whatever technique you're comfortable with. I tried a few solutions using 3D printed parts and a venturi valve, but in the end I used a generic brand foodsaver that was on sale at Walmart. Not the best infusion but weight was still good. 

Basic size adjustments respond quite well within a few sizes (will tighten up next version_ but major changes to the footprint can create issues downstream.

TPU for outsoles and insert (I used Cheetah), ASA for mid-heel, PCTPE for mid-toe 

There are so many choices out there, you can basically get creative and develop your own design using the template as a guideline. Adjusting the template to your own footprint (as adjusted in step 3) could take some trial and error. I used a printed last by Prattotype from Thingiverse.

Using a strong polyester thread or fishing line, stitch through the textiles and into the holes on the midsole components.

Superfeet or other with some good structure.
