I use a super cheap hand grinder I bought off amazon (the stainless steel one that there are 100 different variations of on amazon). There is a plastic part that breaks after about 6 months of usage. Someone modeled and uploaded a replacement piece to Thingiverse. The grinder is cheap enough that it is disposable, but since it is so easy to print a replacement piece with my $179 3D printer, I haven’t needed to throw it away. I hope that at some point 3D printing becomes more accessible and affordable, and with more materials, that more and more products are repaired instead of replaced.

- borgel 7y agoAnother random datapoint. I have been using a Monoprice MP Select Mini V2 [1] for a couple years (similar price point) and am extremely pleased. After leveling the bed the first time I've done no maintenance and it seems to print when asked with no trouble. I typically use it not at all for a few months, then up to multiple times a day when working on something.

- kfriede 7y agoI've helped a friend with this one (I have a MP Select V2 full size), and I can tell you the thing is a workhorse. Pretty sure he has it running 5 days a week with 5-7 hour prints per day. He keeps the moving parts lubricated but that's about it. Just set him up with Octoprint to make the loading and monitoring easier.

- greyskull 7y agoOut of curiosity and ignorance, why is cadmium significant?
- cameldrv 7y agoIt's quite toxic. It causes cancer among other problems. A lot of things used to be Cadmium plated because it's an excellent rustproofer. Some things in the aerospace world still are, because for some things, the safety risk from corrosion outweighs the health risk. It's not a great idea to grind or sand Cadmium plated items, because it kicks the Cd into a fine dust that you will inhale and will be absorbed into your system.
- agumonkey 7y agoSo far I only brushed it, and am not sure my model is Cd plated or not but well. The more you dig into materials, the more you realize you were handling toxic things all the time without knowing it.
- checkyoursudo 7y agoMy father-in-law as a kid used to go to the junkyard and break open thermometers and dump the mercury out into his hand. Seems like he did it a lot. Dunno if he ever suffered any health consequences because of it; but, you know, he didn't know any better. He just thought it was neat.
