Dogfighter - MPX - firewall

thingiverse

This Firewall is designed after the original model, with minor modifications for improved performance. Although the cooling holes are not perfectly aligned, it will still function adequately. The A part measures 4mm in thickness and features all the same holes as the original design. In contrast, the B part has a reduced thickness of 3mm, without any holes, to accommodate the motor and a smaller central hole for non-standard motors. Both parts exhibit similar flexibility characteristics, but I do not recommend using this setup with extremely powerful motors. Standard motors should pose no issues, however. I have yet to test these components in flight conditions. To enhance structural integrity, simply print the parts thicker. In the near future, I plan to release a revised version that incorporates supports from the original plastic part for added stability. The outer four holes are typically used for adjusting the motor angle via threaded screws. However, to achieve greater rigidity, I opt to utilize these holes as additional mounting points, thus increasing their diameter. Unfortunately, the PLA print material proved inadequate in terms of strength. The 3mm B part broke relatively quickly due to its fragile nature. A clean break line resulted from printing all lines consecutively on top of each other. I currently employ an older version of Cura software; it is possible that newer software or alternative orientations could yield a stronger print.
