Namejs knee protector - breathable lightweight knee protector for Latvia military styled pants Part 446

I used modifier for first layers to have soldid bottom layers to protect against sharp objects. Other layers used 10% infill, where sloped and against knee 15% modifier (as in 3mf)- this is important to have pleasant part who touches knee and would not scratch it (feel free to remix it and send me a letter if You make design better please), disable fill angle setting it to 0 and same with Solid infill threshold area, set to 0 as well. Retraction 0. Print with 10 mm/s and with high temperature to bond layers well. Would be best to print with as big nozzle as possible, 0.4 mm would cut into skin unpleasantly, printed with 0.6mm, but I would plan to print with 1mm or bigger if I had. Prototypes printed on Azure film TPU ( https://azurefilm.com/product/tpu-flexible-95a-red/ ), but it is not the best for this task, best is to print with this foamy TPU and it is moust pleasent for skin: https://colorfabb.com/varioshore-tpu-green

However both named materials are best for civilian use, TPU can burn and attach to skin during warfare/ combat, thatswhy use fire safe printing materials for military use, haven't tried theese, but quick search gave me theese, recomend me better ones in comments or trough sending message.

Feedback- please send me a letter or write a comment how it printed for You and how You would improve design, besides that I would be super happy to see picture in what pants it fit in (I am wondering will it fit into other NATO armies and police pants). In future I plan to redevelope this design as an elbow protector.

Please print for yourself and do not sell, if You want to sell I will print some of theese and  demand them in this shop: https://milcamp.eu

Summary

• Material Cost (TPU): €2.50 (per 1 piece not pair- around 90-96g)

• Electricity Cost: €0.80

• Unit Cost / Cost Price: €3.30

Disclaimer: made this to support the troops and police, hopefully they fit into NATO pants, heard about soldiers buying theyr own for huge summs of money and decided to fill this gap giving oportunity to print this solutions for cheap, because otherwise many soldiers don't have knee protection at all and unbreathable knee foam pieces are cut from building materials who are uncomfortable in heat. However- R&D in material and time took enough of resources from me, to hopefully get back something I will sell theese for 25 EUR per pair (and if 3 sets are bought then price is 60EUR), that is including taxes.
