I would go with a High-temp silicon one-piece mold. Pull the piece out, made an insert that will rest on top of the opening, then fill it with a metal. tin or pewter or such. then fill it halfway with resin or poly 2-part putty. toss in an inexpensive knob that has the proper connecter on it and End result would look good and would be very strong... You could also coat the mold with metallic stuff and then just use resin and the knob. lots of options, but IMO, you don't need a scanner. EasyMold (purple stuff) is good stuff to clone objects. and using a ABS knob can take the abuse.




Okay thanks. I surprisingly found some online for about $50 and I'll probably do that.

I'm learning. There is now a Cura profile for this printer on GitHub which took my prints from 50mm/s up to 180mm/s. The thing is rocking like Candy Johnson at a Surfaris show.

I was playing around with vase mode (called spiralize outer contour on Cura) and made a video. This was a test, an experiment. The weirdness you see is just me experimenting with lighting and testing the auto focus. The background music is also me.

I found the model on Thingiverse: https://www.thingiverse.com/thing:2511033

Since we're on the subject of 3D printing (but not meaning to hijack the thread), I have an Ender 3 Max with the original Bowden extruder setup. I just noticed there's now a cheap Creality Direct Drive extruder available for only $38. I don't really have a need for printing TPU (although it would be nice) but I was wondering if it would improve my print quality?

I print mainly with PETG. The first few prints of a new roll come out great but then it starts stringing. Probably because PETG absorbs moist like crazy. I was wondering if a direct drive extruder would lessen the stringing (due to the faster and better retraction)?

But what worries me mostly, is the extra weight. Would the extra weight cause the x-movement to become less accurate (due to inertia)?

I am obviously a complete newb, so I cannot provide any authoritative answers, but this machine has a direct drive extruder and I have been studying. I have only used PLA, but I have a roll of TPU on the way.

Regarding direct drive, retraction and stringing, I found the following video informative:



I never even thought about the additional mass of a direct drive extruder, but I would guess that the advantages would outweigh any loss due to additional inertia. Because retraction would take less time, it might offset the time it would take to stop or change direction along the X axis. If the rollers, belt, etc are in good shape and adjusted, I wouldn't expect any additional slop.

Again, I am not the voice of experience. Just the opinion of an old retired gearjammer.

Another "vase mode" print, this time at full speed. It took just about an hour.

very nice (and spoooooky!)

I went ahead and splurge and bought a new one.
Ender 3 V2 NEO 3D

Appears to be upgraded from my original. As also they bundled it with a laser engraver. Paid like $177. Hopefully it does ok.

Cool, tell us why you chose that one and let us know how it works out.

Don't throw your old one away, donate it. I never sell anything, but I always give stuff away.

Honestly, I have no idea what the main differences are between the models. Seems like very subtle differences and price. I just got it, because they enticed me with a bargain (in my mind). If they wanted to throw a laser engraver (albeit their most weakest one) for under $200 shipped, I'm willing to try again. Maybe I'll give the other one away to some maker place and they can do whatever. I honestly hope I have decent luck with this one. I'm not looking to make to sell anything. Just want to print fun stuff or handy peg board tool holders.

An interesting take on the Ender 3...
