Brickyard Compatible Bolts

prusaprinters

<p>I made these bolts to give my son more options when building with his brickyard set. They have a loose fit (same as original) that allows him to easily assemble them.</p><p>They are designed for easy printing with a large flat head for good bed adhesion and a stepped transition from the socket to center hole that allows easy bridging. The heads do not fit with the “box” end of the wrench, but I felt that was a good trade off since it does work well with the hex end.</p><p>I printed these in PETG with adaptive layer, and 5 perimeters. Perimeters seem to work better for filling in the threads than solid infill.</p><p>I have included the parametric FreeCAD file (.fcstd). For easy editing simply change specifications in the spreadsheet.</p><p>The Brickyard sets can be found at: <a href="https://www.amazon.com/Stem-Toys-Building-Blocks-Educational/dp/B075N8W9VK/ref=sr_1_1_sspa?keywords=brickyard%2Bbuilding%2Bset&amp;qid=1650415328&amp;sr=8-1-spons&amp;spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFQRkRTS1ExVk04UUYmZW5jcnlwdGVkSWQ9QTA5MzM1NjBaQkUyOUFYNFAzSTcmZW5jcnlwdGVkQWRJZD1BMDU4OTU0MzFNNjVBQ1hRSlRBV1cmd2lkZ2V0TmFtZT1zcF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl&amp;th=1">Amazon</a></p>
