Qidi Q1 Pro Lid Spacer

I designed this lid spacer to ventilate the chamber while printing PLA, instead of fully removing the lid as recommended by Qidi. This allows me to maintain a cover that prevents dust and debris from entering the chamber.

These spacers securely snap onto the existing lid lip to prevent accidental dropping into the chamber. The lid can be easily removed and reinstalled with the spacers attached. The spacer can be removed effortlessly but remains securely in place. It elevates the lid 1 cm above the top of the printer, ensuring proper ventilation.

The flat portion of the spacer is designed to fully cover the rubber lid grips embedded into the top of the printer and engage securely with the surrounding hard surface. Using this spacer while printing PLA with the door closed has resulted in chamber temperatures never exceeding 36°C. This is well below the recommended drying temperature for PLA and has consistently prevented printing issues.

Over the past two months of nearly daily prints with a heated bed temperature of 60°C, this method has proven effective. Our printer is located in an unfinished basement, where the ambient temperature typically ranges from 21-23°C. Additionally, using this spacer and keeping the door closed significantly reduces printing noise compared to an open door and removed lid.

To print the spacer without supports, lay the model on the angled side before slicing.
