Protective Cover for Pinion C1.12

Like many people who use a Pinion gearbox offroad, I was unhappy with it being both the lowest point and exposed to impacts from stones from below. I also wanted some protection for the belt drive sprocket, as it's expensive to replace and a single rock can do that for you.

This is a work in progress. My end goal is to print this part with as little infill as possible and fill it with epoxy to make it really strong.

Print Settings

Printer Brand:

Prusa

Printer:

I3 MK3S

Rafts:

No

Supports:

No

Resolution:

0.3 mm

Infill:

25%

Filament: Prusa PETG or ABS any

Notes:

Print with many perimeters (I used 4), also for the bash guard area I highly recommend using a modifier to print this at 100%, which is not necessary for the rest of the part.
I have printed this in both PETG and ABS, ABS is nominally stronger and more resistant to impacts, but getting good layer adhesion is hard. I have an enclosure, do not try to print ABS without an enclosure. PETG is probably easier to handle and almost as strong.

How I Designed This

Contours were taken off a model of the gearbox. This was really hard as many surfaces were faulty.
