Now it's adjustable 5-12 mm 2022 02 21 It's my home tool for recycling PET bottle to filament. This design, based on replaced Ender parts. I had the board, screen, hotend, fans and the stepper motor. I only paid for the PSU 15$ and screws 15$ and the filament 20$. So at all it cost me around 50$. When you have some outdated 3d printer parts in your desk, it’s maybe the time to use it once again. Just with two part remix you can use almost any marlin compatible mainboard and screen to control it. The project goal is to be as cheap, easy build, modify and compact as possible. Work is in progress. Soon I will make detailed installation description. Please consider buying me a coffee if you want to help the process.
