One thought about printable bearings:

Did anybody ever thought about using air pressure instead of metal bearings?
It’s an idea I’m running around for years in my head. Never talked to anybody about that until today.

[RobertKuhlmann]

It’s quite frustrating to see my new parts printed while I have to order and wait for them – I’ve got no own printer yet. 🙁

😉

But it’s very amazing to see my work realized so fast and that it seems to be useful.

I have to explain, that I can design and draw at my office, because I have a lot of idle time at work. But, of course, I can’t work on my real Morgan here. So it’s virtual brother always is a few hours ahead.

One word one loosening bolts:
How about fixing them with special lacquer?

[RobertKuhlmann]

I think the bearings will wear of the rod or vice versa, if they have different degrees of hardness.
Anyway, I like this solution a lot. It’s got the same charm, like the Morgan. 🙂

[RobertKuhlmann]

I think it would be good to use the same steel for the rod, the bearings are made of to reduce abrasion.

RepRap Morgan extended BOM is updated.

[RobertKuhlmann]

You now find a new version under the same link:
http://reprap.org/mediawiki/images/1/1e/12-bed_z_mount_bracket_for_threadless_ball_screw_8mm.stl

I’ve turned the mounting direction of the ball screw 180° so that the tensioning screws are better to handle.
I’ve added some plastic for more stability and corrected the teardrops.

[RobertKuhlmann]

I’ll make a new version that needs less or no support and with more stability. Give me a minute… 😉

…and of course with correctly oriented teardrops.

@Quentin: Yes, it’s done with Autodesk Inventor. I’ll add the new z-bracket to the extended BOM in RepRapWiki (http://reprap.org/wiki/RepRap_Morgan_extended_BOM), as soon as it is ready.

[RobertKuhlmann]

Here’s the z-bracket with a plate for the threadless ball screw (for 8mm this time): http://reprap.org/mediawiki/images/1/1e/12-bed_z_mount_bracket_for_threadless_ball_screw_8mm.stl

[RobertKuhlmann]

Interesting thing!

I’ll make a z-bracket for this one tomorrow (it’s too late for that today and I had wine already 😉 ). And I’ll try it myself too.

Quentin should love it, because he doesn’t like to use threaded rods. 🙂
Even if it rises the vitamin-count for the morgan though.

And don’t worry about the speed. It’ll be fast enough I guess.

[RobertKuhlmann]

I’m doing my own virtual build in parallel to my real build using Autodesc Inventor.

The actual progress is published in the RepRap Wiki:http://reprap.org/wiki/User:RobertKuhlmann/RepRap_Morgan
Along with some notes I publish all Inventor-files over there as well. The actual Inventor-model contains realistic movement capabilties to enable future simulations and movies.

Findings in my project (e.g. corrected platform-holes) go into my extended RepRap Morgan BOM in the Wiki:http://reprap.org/wiki/RepRap_Morgan_extended_BOM

You’ll find screenshots (png), tehcnical drawings (pdf), Inventor files (ipt, iam) and STL-files of all Morgan parts.

Any comment, contribution or tips are welcome.

[RobertKuhlmann]

Hi Quentin,

the printed parts for my Morgan have arrived today. The vitamins are here already and I only need to some hardware to be complete.

But there is one part of the BOM that still misses. You’ve called it “15mm pipe holders”, two of which are needed.

Do you have them as an STL already (You’ll need them to ship the kits I guess 😉 )

Best regards
Robert
