Been creating models and printing stuff quite a lotfor Dollo so here's some updates about my build:
- created a model to attach PSU underneath the frame
- adapter for RAMPS box mount to Dollo bow tie setup (excuse the messy cables)

- printed some extension parts and now Z-axis gows up to 41 cm

- fixed problem with Z-wobble caused by bent threaded rods. I created a rail setup that makes the bed move straight:

- assorted parts

The build volume is now 120x93x413mm. I haven't yet tried how well very tall prints work, planning to do that this week. I fear that the frame isn't rigid enough and causes too much play, especially when Z-height grows. A short ~3cm box was fine, but doesn't tell anything.

I also printed enough parts to expand X and Y axes so the build volume would be 210x210x413mm. That'll need some more parts for the X and Y rails, though and I'll probably need to lengthen some cables also.
