Self FDM 3D Printed PartsHull_front1Recommended material for all parts is PLA. The only non-PLA part is the Lid_TPU, which needs to be printed using soft TPU. I used the RIGID lid option with TPU hardness of shore 72.5A / 16D, but you can get a harder TPU and print a softer lid – see options in the „Valkyrie_electric / Lid“ folder. Total filament weight is under 1kg.
