Building of Mini Kossel 3D Printer – 1
I spent three hours to enlarge square hole in one of top vertex frames.
Tools I used for the tedious job: power drill with 3 mm bit, square file, flat file, and Vernier caliper.
Dimension of the bottom vertex frame.
I decided to buy six vertex frames for 2020 aluminum extrusion after short discussion with a machinist.
Dimension of the push rod mounting plate. This plate is bolted down to a steel linear rail device or a wheeled carriage.
