SG-1000 / SC-3000 / Megacart 3D printed cases - ThingiversePosted: Sun Dec 15, 2019 8:10 pm
Great news. 6mmbrx has developed 3D printing files for SG-1000 cartridge cases and has put a version for the Megacart on there too. I haven't tried it myself, but the finish looks pretty good.
"Depending on the quality, prints of top and bottom shells can take from 6 to 10 hours. I usually print at 0.16mm layer height with a 0.04mm nozzle and prints for this take around 8 hours. The slicer says these use about 60g of filament, you can get 1kg of PLA for $15-20, so each cart will use less than two bucks of filament. No worries using PLA for this. "
So they are slow to print if you are making a lot of them, but the materials cost is fairly low.
I wonder what it would cost to get these printed by a third party service. I seem to recall some of the sites would let you upload a stl file and get an estimate. Has anyone tried that recently?

So you should probably contact 6mmbrx if you ever get grand plans about producing a lot of these :)

I bought myself a 3D printer for Xmas - a Creality Ender 3 pro. That thing is very cool. Cheap, fun to assemble (give yourself a couple of hours), and it has a good build area with a removable magnetic base.
The Megacart cases work pretty well. The finish is a bit rough compared to an original case, but they are very functional.
See attached photos of the Megacart version of the case. 6mmbrx kindly said I could make some to go with the few Megacarts I make, but please check with him first if you want to make commercial quantities.
Some things to look out for if you are printing these yourself.
1. You need to experiment to find a screw which is exactly the right size. I found 4G x 16mm timber screws work well.
2. Be careful with the mount points on the bottom half of the case - it is easy to crack them if you use the wrong size screws or if you twist too hard.
3. You need to use an old soldering iron to clean up the 'stringing' in the holes on the top half of the case so you can get the screw heads sitting flat. Do that BEFORE you try to screw the case shut so you don't crack the mount points on the bottom half of the case.
4. The 'bottom' of the print is the outside of the case (you print the halves upside down so the outside is sitting flat on the print bed). Unfortunately that means any imperfections on your print bed will show up on the outside of the case.
5. I print at 0.2mm layer height with no raft. The prints take about 4.5 hours and use about 60 to 65g of filament.
6. If you want a better quality finish, then use 0.15mm layer height and print a raft underneath the case. That gives you a smoother finish on the outside of the case because the raft sits underneath and gives you a flat surface for the outside of the case. I assume it will give you a slightly stronger mount point on the bottom half of the case too. But that takes 8-9 hours and uses about 85g of filament.
7. You might need to use a craft knife to trim a couple of bits of plastic stringing / over-extrusion to get the cases closing perfectly flat at the end.
I haven't tried the SG-1000 version of the case without the hole for the Megacart reset switch, but the experience should be similar.
