  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area.

3d printed thrust bearing

I printed this thrust bearing, a 2326, 50 mm OD, entirely out of plastic. Plastic races, plastic roller bearings, and a snap fit top race. See youtube below, and it's on thingiverse. I also printed it at 50% size or 25mm OD. It's interesting and will work for light load lazy susan type requirements. Or prototyping till your bearings show up in the mail. I'm going to try scaling 37.5mm OD next.

That's cool. Have you printed much for integral assemblies? An example would be plain roller bearing where the balls are already position in the races. I'm curious if they model them as an assembly maybe even with a defined tolerance gap knowing the 3DP is limited to its nozzle resolution... and somehow it magically prints? I've seen things like ball & socket jointed desk gnomes or like snakes where (I assume) they build little micro bridges between the parts. So when its off the printer you kind of give them a 'come to life crackle' (break the bridges & they they move but the joints remain intact.

I've only done this once or twice with models from other people. I'd like to know about any plain printable roller bearing models which are good, integral assembly or not.
