I bought a Pegboard from Amazon. (https://www.amazon.com/dp/B0BJ16TCMS?psc=1&ref=ppx_yo2ov_dt_b_product_details) and I also got a Backbone One V2 Controller for my phone and PC.

I modified the STEP file from (https://www.printables.com/model/289854-pegboard-vernier-caliper-holder-2-versions)

Have uploaded the Step File just in case u wanna modify it

I printed this in PLA+ (eSun) with 15% infill and works great in Draft(0.24) default profile and I didn't need any supports on the A1 mini

Happy Printing
