My first complicated 3D print. It wasn't that complicated for me since it is someone else's design. Now we need to find a ball bearing or something similar to use with it.

I've also printed 9 einstein tiles.

That's a really cool print (above), can you give me the link? I may give it a try.

I was worried early on, because the interior cross hatch in the lower part was really messy. It was very gappy with lots of stay fibers coming loose. I'm not sure what was going on there. Higher up, where the cross-hatch area was smaller, the problem went away. I haven't tried looking at the design to see if there was a difference in the upper and lower areas. I'm curious to know if you see something similar. I actually paused the print to snip off some strands at one point.

My youngest has a "torture toaster" printing right now.

What was your infill percentage? I chose 15%.

It was 15%. That is the default and, at this point, I don't think any of us have done much experimentation from the default.

The torture toaster came out nicely. The printer did well on all the challenges presented by it.

I printed it this morning, came out pretty good, but not as good as yours as I don't have this specific filament dialed in (mainly temperature, fan). I had checkmarked "avoid crossing paremeters" due to your complaint. I have not cleaned up my print yet.

Strings are usually caused by the filament being on the hotter side of the range. I usually like printing on the hotter side because it provides a better bond and the finished product (after strings removed) usually looks better. Sometimes I will print on the cooler side though, depends on what I am printing and the material I am printing with.

I had a few places with slight separation due to no support under the holes, where the filament has nothing to help hold it up - I wouldn't have noticed as there were only a few, but did notice because I was looking for them due to your print.

I had a few places on the top where the ball entry holes are that had strings, but it is fairly minimal.

I also had some bump defects occur (like near the center hole on the flat section), likely caused by my fan setting being too high and curing too fast causing curling. It also looks like I need to dial back slightly on the extruder rate for this filament.

As a whole I'd say your print looks better than mine, as the PLA brand I was using could use some temperature tweaking & fan adjustment. I'm also using a 0.6mm nozzle at the moment. The print came out nice enough to be usable if I can find a bearing.

I had a bump off to the side of my flat area, too. The white color makes it hard to see in the picture. I was printing with a 0.4mm nozzle and 0.2mm layers.

Update: I found a 5mm bearing. The down feeders work perfectly. Other than that, the "game" looks nice, but is totally unusable. A longer base arm as well as a curved ramp would help as would taller guides.
