A modern take on a Kossel

This is an experiment to build a Linear Delta Printer using four towers instead of three. Primary reasons: 1. Build area is roughly cubic vs roughly cylindrical 2. Greater speed and precision from additional control provided by fourth tower. 3. Symmetric kinematics from even number of towers.

My large printer design. 400mm build plate, ~1000mm build height. Most of structure is 8020 but the sliders are V-Rail

A Rostock style delta bot with the parts which are typically 3D printed made from medium density fiberboard (MDF). It uses a home made hot end.
