yeah i figured i would start with some easy grey pla then if i dial it in then move to what i really want to use which is some wood filled pla.
First attempt at modeling from scratch.
The blue one is my first attempt at a knurled replica of the Reactor. I don’t have a caliper yet so I estimated dimensions and got them a little wrong. It’s also a little light. V2 is on the printer now.

Looks good. What modeling software are you using?

I’m doing everything including slicing in Fusion 360, but I’m thinking of trying a different slicer as it doesn’t seem to automatically support brims and rafts, and I can’t figure out how to convince it to slice a few parts sequentially instead of layer by layer in parallel.
I failed bed adhesion twice on this print so I’m revisiting… I haven’t started using a glue stick yet but it’s the next thing I’m trying.

Even if it seems fine wash your bed and re level as well. That’s usually the culprit when I have bad adhesion or my z offset is off. Over time those bed springs shift

I will definitely do this next time 
I’d recommended design in Fusion and slice with Prusa Slicer.
For losing bed adhesion I’d recommend using Elmer’s purple glue stick and clean with water/paper towel and reapply every few prints. Also use Gyroid infill to avoid the nozzle hitting the infill. I usually set my zhop at retraction to 0.5 mm as well.
If these don’t fix use raft or 5 line brim.

I’m going for 100% infill for weight. Does the gyroid pattern make a difference at that point?
1 Like
No. Not at 100%.
Gyroid just avoids the nozzle crossing over the infill pattern like it does in rectilinear.

You could try like 97% Gyroid and it may help.

I’m past the failure point on my prior prints so I think the glue worked. I might try it anyway…
I’ve been modeling throws tonight. Not sure if I’ll get around to printing.
I have some shopping to do; I think I want a second color material, I need a bunch of tools, and I maybe want to bang together a raspberry pi, octoprint, webcam setup…

The start of going down the rabbit hole.

Other half turned out identical which is a good thing in this case so I’ll sandwich these together and see how they play before tinkering and junk

I have a raspberry pi 4 with web cam and sd card setup for octoprint if you want it for cheap.

What’s the axle gonna be?
Haven’t looked through my parts box but I’m pretty sure I have a wood dowel that’ll fit it perfect. If not I might 3d print something until I get a chance to hit the hardware store.

Highly recommend wood. If using printed axle decrease the gap width.

V2 (middle) turned out pretty ok. Hit the goal weight of 10g. There are one or two tweaks I would make for next print, including trying to make the channel a little deeper and the knurl pattern a little bigger, but it plays.

Here’s my most recent version. I think the knurling geometry looks ok but the channel unfortunately looks sloppy 
. It’s got the right play feel but not a looker yet…
