This is a small size desktop 3D printer. I have noticed most of the parts I print are small and I was looking for a second 3D printer.

Features

Build Volume X: 100 Y: 100 Z: 100 Quick and Accurate It uses a short bowden tube setup with a high torque extruder. Thus it was possible to design a light weight printhead for quick travel moves. Belt tensioners are integrated as well as an adjustable Z endstop. Silent Uses Trinamic's TMC2208 stepper motor drivers with high torque and speed in ultra silent operation. Clean Comes with cable management. All axis use drag chains for durable and clean wire guidings. Affordable Common parts Easy to use preconfigured Marlin firmware and Slic3r profiles

Use it for the arrangement of the parts. You need a compatible reader, most third party does not support 3D. I needed to install Adobe Reader. Filment path: for better print quality with hard to rotate filament spool holders, mount the bowden strain relief to the 2040 Z exstrusion, above the ramps board.
