.STL being sent to you now. Must admit I didn't twig.

You are a bit late, I have made the .stl and started printing it an hour ago!

Lol! Cheers.

Thanks for that. Looks pretty good in the photo. Any gaps? All looks pretty tight. I'll pm the address thanks, be interesting to see someone else's attempt. Wall thickness here btw was 1.2mm so a multiple of the 0.4mm nozzle.

Lad did copy the original, originally, with the handle higher up.

I left him to draw it (done in Fusion) with no oversight by me. Looking at the one he's done he could have radiused the bottom and vertical rear edges.

How long did it take, temperatures and what material?

Thanks again.

Seems fine to me. Wall thickness measures 1.6mm but was 1.5mm on your design.

Your version is better for all but the bottom row.

There is a missing fillet in the front bottom (ooh err!) too.

Three and a half hours in transparent PLA. Might have been eSun, not sure. 210 nozzle and 65C bed.

I was inspired to do some long ones too, if anyone wants the .stl? I haven't put in the slots for the dividers because I think it is superfluous and I throw the dividers out.

ajlelectronics · Oct 24, 2021

Or how about one that is bisected? Probably more useful than three loose dividers...

Cheers. What speed and layer height was that?

50mmS and whatever Cura defaults to which is 0.2mm. I can look it up tomorrow though. I also have Z seam set to random to get rid of an annoying seam down the rear of everything.

I will be able to run the printer tommorow as we have been cleaning and fitting vinyl 9ver the weekend

I drew this up in fusion and printed it last week. Also printed some 22mm diameter simple cones.

They were bits for my granddaughter's cosplay prop for last weekend's Comic con.

Just a question for all you 3Ders, has anyone printed slip-on plastic jaw covers for a lathe? Strikes me that they would be good when holding easily marked work pieces when turning?

I've searched the usual suspects but can find none commercially available?

Can you draw it, with dimensions?

Could do - would a pic of the chuck in situ on the lathe (Myford ML7) with measurements do?

ajlelectronics · Oct 25, 2021

It needs to be descriptive enough to be able to CAD it. I am sure that photos would help to give context.

I am sure it could be done quite easily with relevant measurements as ajelectronics has already said. I don't know how practical they would be though as I think the jaw pressure on them would cause them to split easily.

Thanks, I'll try to get them done tomorrow.

Hadn't considered how easy they would split, I think I've some copper pipe offcuts which I could flatten and beat into the required shape.

Thanks @ajlelectronics for your interest :hug:

. As you were folks, nothing but stupid to see here ..... :doh:

One of the plastics will be fine in compression.

Mine came out ok . Few wisps inside the box but took over 4 hours.
