Material guide
Here is a list of materials recommended for printing enclosures using FDM printer
PETG (Polyethylene terephthalate) is all round winner. It prints almost as easy as PLA. It is strong and has working temperature of up to 80C.
Printability ★★★★☆
Durability ★★★★☆
Temperature resistance ★★★☆☆
Price ★★★★☆
ABS (Acrylonitrile butadiene styrene) is good thermoplastic used everywhere. It is strong, has good working temperature of up to 90C. It is although harder to print. Needs enclosure to print reliably, warps, shrinks upon cool down. For printing enclosures you need to scale model to 101% to allow for shrinkage.
Printability ★★★☆☆
Durability ★★★★☆
Temperature resistance ★★★★☆
Price ★★★★★
PC (Polycarbonates) Strongest of the three. It also has highest working temperature of 130C. It does require enclosure for printing. It warps even more than ABS. It also requires a printer hotend to work in around 300C+ and heatbed to heat up up to at least 110C. probably most expensive of the three.
Printability ★★☆☆☆
Durability ★★★★★
Temperature resistance ★★★★★
Price ★★★☆☆
Here are some filament brands i have tested to print successfully:
Devil design PETG
3D Prima PETG
3D Prima TPC
HobbyKing TPU
eSun ABS
Bolt dimensions used for modules
There are two bolt types used, standard and shallow
Standard bolt sets(00002528-M5X12-SUS) adds to the module:
Internal cell tab - 0.6mm
Bolt with washer - 5.4mm
Total - 6.0mm
Series bus bar - 1.0mm
Total with series bus bar - 7mm
Shallow bolt sets(ISO 7380-2) adds to the module:
Internal cell tab - 0.6mm
Shallow head bolt - 2.75mm
Total - 3.35mm
Series bus bar - 1.0mm
Total with series bus bar - 4.45mm
Thread lock use advised!
