Dollo 3D Printable 3D Printer

I've been printing and hacking away with the design for some time and I've got a build that works quite well. The quality isn't very good at the moment but getting there. The design itself is not the problem, getting the parts printed right is. For me the whole process of building this has been a bit of a learning experience in part tolerances and printer calibration . Also I've done some remodeling and new models as needed.

Couple of latest prints:

Anyone else with working Dollo or printing one?

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.
