The M2.5 insert socket on this part is made for a 4.6mm diameter insert, like the <a href="https://www.prusa3d.com/product/threaded-inserts-m2-5-standard-100-pcs/">CNC Kitchen part available from PrusaPrinters</a>, rather than the 4.1mm-diameter <a href="https://www.mcmaster.com/94459A439/">McMaster Carr part</a> originally listed. Sorry about that!</p><p>This is one of my first models with Fusion 360 so any feedback or recommendations are very welcome. Thanks! :)</p>
