This project enable the use of the MOST-delta printer off-the grid using solar power. These modifications not only makes the solar powered 3D printer a valuable tool for poverty alleviation and wealth creation in the developing world, but it also gives any 3D printing enthusiast the freedom to safely transport their printer to a remote camping site or any location of their choice. The modifications steps involved the following;\n\n* PV system sizing - 60 W system.\n* Coming up with the bill of materials (BOM).\n* Designing and construction of a PV power supply system (fig.4).\n* Designing and printing of solar panel holders (For safe transporting in a duffel bag) (fig.3).\n* Design and printing of battery casing holder(mounted on top side of the top plywood board)(fig.5).\n* Mounting the power supply under the top plywood board (inner-side).\n* Design and printing the Melzi board casing (for protection during transit)(fig.6).\n* Customized spool holder (easy to assemble) (fig.2).\n\n== Bill of Materials ==\n\n* 12V/1.35A 25W solar panels x 3 [http://www.amazon.com/ALEKO%C2%AE-25W-25-Watt-Monocrystalline-Solar/dp/B00BGDRHGU/ref=sr_1_3?m=AVKV7ZKO6OFXQ&s=merchant-items&ie=UTF8&qid=1417733008&sr=1-3&keywords=ALEKO%C2%AE25W+25-Watt+Monocrystalline+Solar+Panel]\n* 12A/100W 4.5-30V to 0.8-30V DC Buck Volt Converter x 2 [http://www.amazon.com/DROK-4-5-30V-0-8-30V-Converter-Regulator/dp/B00C4QVTNU/ref=sr_1_4?ie=UTF8&qid=1417989973&sr=8-4&keywords=buck+converter]\n* Li-ion 20Ah battery (includes PCM with balance function)[http://www.batteryspace.com/polymer-li-ion-rechargeable-battery-pack-14-8v-20ah-296-wh-----un38-3-passed.aspx]\n* 36\" Duffel bag[http://www.amazon.com/High-Sierra-Bottom-Wheeled-Duffel/dp/B004FX1WGO]\n* Bolt with nuts x 3\n* LED x 2 [http://www.amazon.com/TOMTOP-50Pcs-Light-Discrete-Luminous/dp/B00CGVA6CS/ref=sr_1_10?s=industrial&ie=UTF8&qid=1418244976&sr=1-10&keywords=led+diodes+red]\n* Switches X 2 [http://www.amazon.com/SPST-Momentary-Rocker-Switch-250V/dp/B0094GC6SK/ref=sr_1_7?ie=UTF8&qid=1416875426&sr=8-7&keywords=24V+rocker+switch]\n* Diodes x 5 [http://www.digikey.com/product-detail/en/SB560E-G/641-1420-2-ND/2075756]\n\n== Source Files ==\n\n* [[File:Panel 2 holder.stl]]\n* [[File:Panel 2 holder.scad]]\n* [[File:Panel 2 holder midsection.stl]]\n* [[File:Panel 2 holder midsection.scad]]\n* [[File:Battery casing final.stl]]\n* [[File:Battery casing final.scad]]\n\n== Tools ==\n\n* 5.5mm nut driver\n* Sharp x-acto-like knife\n* Small, flat bladed screwdriver\n* No.2 Phillips screwdriver (a power driver is best)\n* 1.5mm allen wrench\n* 2mm allen wrench\n* 2.5mm allen wrench\n* 3mm (1/8\") drill bit\n* 8mm (5/16\") drill bit\n* Tape measure (large calipers >300mm are better), preferably metric\n* Soldering iron\n* Wire strippers and cutters\n* Needle nose or other pliers\n\n== Consumables ==\n\n* PLA\n* Connector wires\n\n'''Note that all of the pictures in the process can be enlarged by clicking on them.'''\n\n{{Page data\n| license = CC-BY-SA-3.0\n}}\n\n[[Category:MOST methods]]\n[[Category:3D printing]]"}
