Robert) I dont wanna hijack anything either so i will try to be brief.

"Will it work?"

Yes, and IMO if the screen resolution is high enough, then a resin type printer should spit out the better print. Otherwise, an FDM will work equally as well.

At first, i thought this was going to be a detail part to be added to a model. Now that we know its just a lamp post.... plus youve produced a purty good *.stl file judging by your prints, this shouldnt be that hard for a well dialed in printer.

If you're still in need of these printed, I can do them as detailed as 0.05mm. Just let me know.

If you're willing, I'll take you up on the offer. I am interested in the one with the caps. As stated earlier, 25 would be the needed quantity.

The .STL file has been uploaded to my meager Thingiverse account. It can be found by searching for 'Lamp Post Base' in the 'Buildings & Structures' sub-section of the 'Models' category.

The first file has two bases: one with open ribs, and one with corner anchor bolt covers. This morning I added a second file with just the covered corners version to make it easy to assemble an array of 25 or 30 bases on the 3D printer build plate.

Progress.

Second attempt at printing. A 3-by-3 array of the selected base.

The elephant foot at the build plate adhesion zone is a little less, but not entirely eliminated, and the overall fattiness is lessened as well. Minimal clean-up and sanding would smooth out these issues. Lapping (polishing) the build plate with a 1200/3000 grit water stone might help, and a new bottle of resin wouldn't go awry either. Still not great, but almost getting to the point where these wouldn't be embarrassing to have on the layout.

Layer height 0.04mm, two base layers, 35-second base layer exposure, 5-second upper layer exposure, 63 degree ambient room temperature, relative humidity about 20% (I live in the high desert of Wyoming), print time of about 5 minutes.

Here is the latest (and last) iteration . . . a 5-by-6 array of 30 bases. Send me a PM and I'll arrange to send them to you.

Hi Robert,

Those look really good!

Mr. Robert: As I can't get the PM system to work on my devices, I'll go this approach. Send it to: Removed by request, Miles City, MT 59301. Miles City is small enough that it will find me.

Thank you for all your assistance.

Okay. Got it. Now I suggest that you edit your previous post to remove any personal information.
