They work. Just need a gridfinity container to place them now.

If you need bearings for a print roller, prototyping, dry fitting or anything simple like that, these are great. Save yourself a couple bucks and waiting for amazon to deliver.

These printed nicely in petg. I didn't have a separate petg color for the text, so I used PLA. It actually worked really well. The letters are nice and crisp easy to read. I printed the lube tool and gridfinity container to go with theses. Nicely done.

10/10 This is probably one of my favorite models. I threw my helping hands in the trash the other day I was so frustrated with them. I wish I had found this years ago. For anyone having issues with tolerances, you need to probably decrease your flow rate slight 1-2%. This thing prints GREAT!

The plug slots could be a bit more snug.

printed great, works great
