NeoGeo CD Drive Repair

thingiverse

I got the opportunity to repair a NeoGeo CD drive that had failed. The NeoGeo CD used over-molded plastic parts to hold all of the important gears that open the drive in place. Apparently that is a common failure on these drives. A drum shaped gear sits under the main drive gear and lifts the laser assembly. The cage that supports that drum gear fractures, the only way to fix it is to glue it which is not a long term solution. My replacement cage fits into the same spots but rather than an over-molded part it screws into place making it a replaceable part if it fails in the same way. You will need to print the files named NEOGEO CD Drive Spacer, and NEOGEO CD Drive Drum Cage 1.6 In addition to the two printable parts you will also need to source 4 or 5 M1.8x4mm screws, These are typically found in gameboy replacement shells (where I got mine from) they can be longer if you have something laying around. In addition to the parts to repair this I modeled the gears, they are untested, I do not have equipment precise enough to print these so I could not test. I also included a STEP file for each of them in case someone does need it and my STL files are not right they can use the step files to make adjustments to make the gear right.
