Cool, thanks for that trick.

Still going like the energizer bunny.

Print is progressing slowly, but the surface finish seems to be pretty good, so that is a fair tradeoff I guess.
We will see what happens as the curve progresses.

This thing is big (almost 8 inch diameter).
Not sure if the print will finish on one roll of filament.
The Prusa is suppose to recover if it runs out of PLA.
Surface finish so far is not bad.
The very long print time is making me rethink the corebox idea.
Two coreboxes = approaching 3 days of printing.
I guess it is not tying me up by printing, so maybe we let it print whatever.
I need larger filament rolls on this machine.
Wall thickness looks about right.

A hand included for scale.

Has anyone tried to bead-blast a PLA pattern ?
Seems like that may even out the grooves, and perhaps give a uniformly rough surface that could be shellacked and sanded.
It may also close the grooves.

I used the sanding sponge on the first misprint piece, and it cleans up pretty well, even on the beaded area.
The 2 inch diameter disk and slow speed make it pretty easy to get into tight spots/curves.
The sponge sort of scuffs/melts the ridges off the top, and fills in the valleys.
Very slow rpm it the key to using a sanding sponge on PLA prints.

The faceted surface is rather a pain, but hopefully I can find an option in SW to cure that, and buff that out of this pattern/and or the permanent aluminum pattern.

The print is slowly getting done, and is going faster as it progresses up in height.

This has 10% infill, and that seems to be very strong since the surface is curved.
I have resorted to drilling a hole and epoxying in a wood dowl, to use as a screw pulling point on 3D printed patterns, and I may have to do that with this pattern.
Hopefully I only need to pull it once.
