A low-rise stand for the Alienware 15 R3, meant to improve ventilation for the cooling fans if you're using it on soft surfaces such as carpet or a bed.
The included .3mf files have the supports set up for successful PETG bridging. PLA will work fine, and you can probably remove every other support enforcer if you're printing in PLA (though I haven't tried bridging to that extent to see how it performs).
The dovetails should be tight, but fit successfully. Nonetheless, I recommend using PrusaSlicer's "cut" feature to print out just the dovetails to make sure they will work with your printer.
Fusion360 base file included if you need to tweak the dovetails to cooperate with your printer.
