It's freebie Friday!! Here's a simple, 3D-printable ToF (Time-of-Flight) distance sensor mount designed to fit three different circuits – my VL53L4CD sensor (coming soon), and two different form factors commonly available on AliExpress: Get it on Tinkercad: www.tinkercad.com/things/6DugU...

Three different ToF distance sensor circuit modules (foreground) in front of two white 3D-printed ToF mounts (background). The front left VL53L0X-V2 sensor uses a form factor commonly used for a variety of VL53Lxx circuits on AliExpress, the front middle circuit is VL53L0X design with a protective window over the sensor, and both of these are connected to Adapt-2-QWIIC circuits that provide these with QWIIC I2C connectors. The blue, front right circuit is a compact VL53L4CD sensor with rear-mounted QWIIC connectors. All three designs fit the 3D printed mounts – the rear right mount as a VL53L4CD circuit mounted in it.

A collection of five small pushbuttons sitting on a white desktop. The three left-most pushbuttons have two long leads that fit breadboards securely. The two pushbuttons at the right have four, short leads designed for circuit board mounting and often don't reliably connect in breadboards.

A white USB-C cable is plugged into a blue circuit board connecting to both power rails of a breadboard containing a microcontroller circuit. Two other small blue PCBs and a small purpler PCB are also connected on the breadboard.
