First one done, everything seemed to work, assembly was relatively straightforward and the instructions were great.

Changes - buffer tubes were printed separately with variable layer height in Orca, I've read this helps feeding filament, settings:

Adaptive height 0.08, radius 4.

Triangle Lab kit only seems to come with long springs for the buffer tube, so you'll be building the long stroke version. I wasn't aware there were multiple versions so no loss. They are on the BoM though, so hopefully it saves someone else having to scour the instructions to see if the "missing springs" are needed.

I think I'll try printing the housings for the next one with support, some of the overhangs are a bit misshapen and had to be cleared out with a drill bit. This may still bite me further down the line when I need to fit the module to the base.

It seems like it shouldn't be too difficult to take apart if necessary.

I'd think about bending the solder tabs on the motors before soldering as well, it's a bit of a squeeze inside the housing and it's harder to bend them after.

Hopefully I'll get a second housing printed this week and at least another module assembled at the weekend.
