Does your Famicom have a gnarly eject lever? Is it broken? The 40 year old brittle plastic is becoming problematic these days. I have modeled a super reinforced strong version using PETG for really good strength. I test fit each part on a jig I made from an old crusty Famicom to make sure these levers slide easily and they snap right in. The finish is slightly more glossy than original has since it is PETG. I am experimenting with "fuzz" setting in the slicer to give it the slight texture the original. The last two images are a side by side comparison of an original and my 3D print.
