[pins2cablewidth(# pins),cable thickness,side,x offset,y offset]\n** side starts at 0 on the ISA bus side and increments as you rotate counterclockwise.\n** x offset is from bottom left corner of PC104 module (when the side is facing you).\n** y offset is from the center of the case.\n\n=== Mechanical assembly instructions ===\n\nRemove flashing and push.\n\n== Costs ==\n\n{| class=\"wikitable\"\n!

Approximate Cost\n|-\n| Plastic\n| ~150 grams per section on average\n| $3.33\n|}\n\n=== Current issues ===\n\n* Rendering time is excessive!\n* Tab dimensions don't always match on the bottom of the mid section and top\n* Clips don't always fit together perfectly\n\n=== Possible solutions ===\n\n* Simply model & lower resolution\n* Fix tab code\n* Increase tolerances on clips\n\n{{Page data\n| keywords = 3D printing, PC104 stacks, automation, modular case, plastic\n| sdg = SDG08 Decent work and economic growth\n| published = 2015\n| organizations = MTU, Michigan_Tech's_Open_Sustainability_Technology_Lab\n| license = CC-BY-SA-3.0\n| language = en\n}}\n\n[[Category:3D printing]]\n[[Category:Plastic]]"}
