Thanks Q! I just changed the stl a bit and made a counterbore on that end. I didn’t worry about threads because I have a tap. You could probably get away with no threads because the threads are shallow.

I’ll post up some dimensions.

I have push fits on my other printer and wouldn’t be without them. Not entirely necessary but a nice upgrade!

I’m waiting on some taps and stuff to make the hobbed adapter. Hopefully I can help some folks out who don’t have the equipment to make one.

Congrats on printing!

Is that an E3D V5? I haven’t fired mine up yet but a friend who has one says to keep the fan running all the time and to keep it on post-print until the temp reaches about 50C.

Keep at it and you’ll be printing cool stuff in no time \o/

It sounds as if you need to fiddle with your E steps and retraction a bit.

It printed pretty well:

I was thinking about painting it red to give it a “steam valve” look. Gonna have to keep paint out of gear teeth though…

I also rigged up a simple slip fit extruder bracket that will make it easier to remove the assembly for fiddling. It seems pretty secure for now so hopefully it will stay put during operation.

Thanks Q! I thought 6 spokes a bit busy:

I’ll upload stl after I print it if it looks OK.

Another piece of the puzzle came in:

It’s been kind of nerve wracking testing without a switch 😛

[hoff70]

I too love the design! Poetic is a good description.

Glad you got the tubes worked out \o/ And I like the etching on your plates! Please sand the lettering off the tubes or paint them or something 😀 Your build is looking sweet so keep it clean. Don’t know why but that bugs the crap out of me…

I’m still thinking about an acetone transfer, just not sure where or what 😀

The plain 5 spoke gear on the extruder is just way to pedestrian for a Morgan:

[hoff70]

Sure, I’d be glad too. I’m working looong shifts all weekend but I’ll get you some measurements.

I have a heated bed on my other printer and just measured the 4 corners and left enough room for error. I want to double check that it’s good before giving you dimensions.

It’s made from an aluminum road sign that I liberated \o/

[hoff70]

Working out the extruder:

I know the plans call for it to be located beneath the top plate but I like to watch the gear spin!

[hoff70]

Oh Quentin, You say you used a 6mm tap for hobbing?

Thanks

[hoff70]

Awesome! I have some bearings on order and enough brass stock to make several hobbed adapters. I’ve hobbed a couple of steel bolts and I’m hoping brass will be a little easier to work with.

I was a little worried about the press fit small gear but if it gets the Q seal of approval \o/

[hoff70]

Glad all is well!

Yes, development takes time and money and frustration and failures…

[hoff70]

Oh yea, the build is looking sweet!

[hoff70]

Thanks for the toner transfer tips!

You may be OK on your pipes. They do kind of “wrap around” each other which makes the structure rigid.

I didn’t have any luck bolting my end caps to the wood and doing assembly. I assembled the caps onto the tubes and placed the bolts thru. I also epoxied the nuts into the end caps to hold them in place.

Perhaps you could get away with just dropping the bolt thru the remaining cap and leave the other bolts in place? That would save you some time and aggravation.

[hoff70]

Damn 🙁 I’d double check and make sure my printed parts are correct dimensions. There are files for 8mm and 10mm (I think) rods so that may have gotten crossed up as well.

I’m interested in the acetone transfer stuff if you care to elaborate.
