I was searching for something like this, as I didnt find it I made my own, ugly but function properly, I really like this small printer has been so reliable after thousands of hrs printing, so im still using it, what I never liked was the bed, im not a fan of that build tak wannabe surfaces, so I always used the finder bed on the glass side.
I have other printers but I still use a lot this small printer, I can say its my best printer for PETG small pieces, in the pictures that its PETG.
The bed base after hrs and hrs of printing the bed started to become lose, what is lose its the crystal itself the plastic base doesnt hold it strong enough anymore. As I had a monoprice maker select ultimate that I have to return and I dont have anymore I ended with a borosilicate glass of that printer, so this base its made for this crystal:
Bigger glass more area of printing also...
The model its made for use the finder hardware so nothing else is necessary than the prints, the clips are made for hold the glass in place, for me are not really necessary but that will depend on your printer dimensional accuracy.
You will need a printer bigger than the finder for this, im a noob so I really dont have the skills for make this in smaller parts (2-3 parts bed) w/o lose strength and flatness.
As the finder have no heated bed PLA its good enough for this.
The intention was to make fit everything really thigh. So will fit thigh if your dimensional accuracy its not good enough you may have sand a bit
