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.

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.

A modern take on a Kossel

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