Formula Student / FSAE racecar . Modeled for fun, based on my time in FSAE at university, as a surfacing excersize as well as DFM.
Needs supports, as well as M2x5 (or M2x4) countersink screws. You may be able to use fillament pins if you shave them down to ~1.4-1.5mm, or use glue.
The author marked this model as their own original creation.
