It depends on the accuracy of the 3D Printer.
M5 Paper requires high accuracy.
You need a high-precision printer.
The accuracy of the printer for amateurs is about 0.4mm width.
I think it is impossible because the accuracy is low.

Hello @Dieter_P

I don't own ATOM Lite (ESP32-PICO-D4), so I haven't checked it.

Does the problem occur when using WiFi?
You need to check the signal of GPIO39.
：

In M5Stack (ESP32-D0WDQ6-V3), there is a case where GPIO39 works without permission when using WiFi.
M5.BtnA.wasPressed() conflicts with WiFi

Supplement：
Example of using GPIO39.
M5Stack Basic (ESP32-D0WDQ6-V3)：PULL UP with 100KΩ.
ATOM PSRAM (ESP32-V3-02)：PULL UP with 5.1KΩ.
M5Stamp Pico (ESP32-PICO-D4)：PULL UP with 5.1KΩ.

Hello@ Windorey

The library for fast rendering is LovyanGFX.
It has the function of DMA.
LovyanGFX is about 3 times faster than TFT-eSPI.

：
The authors of LovyanGFX have created M5Unified.
M5Unified is he faster than M5Stack.

Hello@admiralmaggie

It depends on the type of HDMI Display.

Not Display Module 13.2, but...
For ATOM Display and TOSHIBA REGZA：

(640,360,60);
(320,180,60,1280,720);

The cause is the ESP32 bug.

M5Stack Community :
M5.BtnA.wasPressed() conflicts with WiFi
https://forum.m5stack.com/topic/3262/m5-btna-waspressed-conflicts-with-wifi

This is a report of measures for the A button of M5Stack and the B button of M5Stick C to operate without permission.
ButtonA on M5Stack does not work properly : May 02, 2021

void setup(){
WiFi.begin();
WiFi.setSleep(false);
}

or

#include <driver/adc.h>
void setup(){
