Leaf battery module spacers

Printable light weight spacers to replace the heavy steel ones in the battery pack. For a typical 48V DIY powerbank with 42 modules you'll save 4.6 kg. I'm building mine on a trolly so keeping weight down will make it easier to manage. 42 steel spacers (top and bottom) weigh 5.5 kg, where as 42 PLA spacers weigh just 0.8 kg. I printed 5 pairs at a time on a Bambu P1P bed (256 x 256 mm), which took 3hrs and 104 grams of filament. I used fuzzy skin on the outside edge to reduce warping hopefully/…
