How would you guys print this: https://www.thingiverse.com/thing:260546/files

Need about 50cm - so was thinking two 25cm pieces

I would print it vertically, using a raft or large brim. Length would depend on my max Z height of the printer, but 2x 25cm should work well. Just make sure you have retraction on as the higher it gets, the more liklihood of wobble and the print head knocking it. Slow the speed down a bit once you get past 15cm height if needed.

You should be able to print both at the same time, place them about 1cm apart on a large raft or inclusive brim, use blue painters tape if needed on the brim/raft;)
 
Thanks, also thought standing up.. printers Max height is 250mm, so will be interesting
 
Can maybe do 5x 10cm to keep it safe. Its for a parking sensor, so doesn't need to be pretty.

Problem I'm seeing, when I slice it vertical, it seems the parts aren't all connected.

Good luck!
Have you got an inverter?
We had 3 rounds of 4/2hr LS yesterday and this morning, 26 hour print still going strong. Best investment ever LOL.

I have one for camping :D But can't remember the rating - will need to dig it out.... fortunately it looks like we only getting a power outage again tomorrow.

Max I'm drawing at present with bed at 60C and nozzle at 208C, both obviously kick in and out, mainly the bed - 1.4A and about 240W

Probably work off my camping setup then. Think its a 500w inverter, but not pure sinewave.
 
Print is almost done, hopefully works with the led strip.

Next up is the electronics housing for the electronics and cabling.

So for the printing is going better than my programming...

A bit like the twin towers - fortunately it stayed up. Busy tiding it up - then glue.

Just kicked off the second part - electronic boxes, says 4h49m - and we have load shedding at 12am - so here's holding thumbs.
 
Looks like I won't be finishing tonight. Fighting with a new problem, first layer goes on fine, second one is screwed.

What I did to limit effect of loadshedding was to hook a 12v deep cycle battery directly to the DC inputs on the controller. Bypass the power supply completely. Then I just keep the battery charged with a charger. Worked well for a long time.

Anyone have any ideas what else I can check why it starts doing this on the second layer?

I've checked belts, eccentric nuts, tried different temps, tried changing the flow, releveled the plate, tried different models, cleaned the nozzle (its probably only three/four prints old anyway).

Every time - as soon as it gets to the second layer, it seems to under-extrude randomly.
