Gameboy cartridge - complexities

ive been chipping away at this edge for days now and im giving up and asking the community now.. since we dont have the proper variable chamfer tool, im not sure the best workaround. here is my current progress:

et voila..? has a curve in it which is weird but.. yeah not sure if that is right. my main issue is i’d like to be sweeping to a different triangle face instead, along that spline i drew. currently im only able to sweep using the one chamfer profile.

heres what happens when i sweep with two faces and the spline selected. lol..

weeeeeird. anyways, if anyone has ideas… thanks

thanks for your attempt! i am trying to taper the back edge fillet from big to small. see the 2nd image with the faint orange lines :stuck_out_tongue: i was hoping i could sweep between two different sized chamfer sketch profiles but it glitched out for me like in the last photo, so i’m not sure what other workaround there is.
