Here’s a monobloc breakout for a Nano: ![monobloc for nano](https://canada1.discourse-cdn.com/flex028/uploads/core_electronics/original/2X/d/de3f860ff83a7911892802420cdd7a096a80f721.jpeg) Jumper pins can be inserted into the holes. More secure than with a breadboard.

Hi John, Nice stuff. Breadboards can be finicky so I’m glad to see that you’ve made your solution open source. Keep it up! ---

Hi John, Great stuff! How are you running the wires in this revision for those who want to make one themselves? ---

You can print the entire bloc oftwo rows of 15 pins, or smaller blocs for just the pins you intend to use: ![20240519_124907](https://canada1.discourse-cdn.com/flex028/uploads/core_electronics/original/2X/8/844eda86c4c6a509c66ce5b548b141b8492479d1.jpeg) Thread the stripped wire thru one thru-hole, bend it over & insert thru the other thru-hole: ![20240519_125032](https://canada1.discourse-cdn.com/flex028/uploads/core_electronics/original/2X/2/2830cc34727ca1348c9cf03808a9c09529932072.jpeg) ![20240519_125104](https://canada1.discourse-cdn.com/flex028/uploads/core_electronics/original/2X/7/730c9b0a459a4704cef51efa4e78ac1c9e64d879.jpeg) Press down with something hard to square off the wire as best you can: ![20240519_125212](https://canada1.discourse-cdn.com/flex028/uploads/core_electronics/original/2X/7/70ff3839c2a4b54065f2f0c23298e72f21001997.jpeg) Set the wire into the PLA with a hot iron so that it is held in place: ![20240519_125316](https://canada1.discourse-cdn.com/flex028/uploads/core_electronics/original/2X/7/75b88072fb8df161c90dca2ae49900cd6813ed74.jpeg) Trim ends: ![20240519_125507](https://canada1.discourse-cdn.com/flex028/uploads/core_electronics/original/2X/6/6deae62794f6fe1735a0f6946383edb8a2f7b329.jpeg) Test for a tight pin to wire connection; good idea to insert a jumper into each thru-hole before setting with the iron–that will ensure the jumper can be inserted: ![20240519_125836](https://canada1.discourse-cdn.com/flex028/uploads/core_electronics/original/2X/4/49cd469e7cee72db52195cb12ce6ecf4de372afd.jpeg) ---

Hey John, Nice revision, and a great idea to sink the wire into the block with some heat. Always happy to see people using heat to process printed parts, I think its a heavily under-utilised method! Cheers, Jaryd
