heat-set bore F360

thingiverse

Determining the optimal settings for heat-set inserts is no fun at all and can be quite tedious. I've created a #fusion360 template with user parameters to simplify series modifications. The STL uploaded meets the requirements for "thingiverse publish." Just a heads-up: offsets are specific to the insert, plastic type, and hole orientation - horizontal versus vertical. So you'll need to figure out your own offsets for the nut insert. The central bore in the test piece is of the standard size. Bores to the left of this size are smaller, while those to the right are larger. This particular file was created for my tests with McMaster Carr M2 short heat-set inserts. Some notes on the user parameters in F360: thread_bore: diameter of screw threads (with offsets) root_flange: diameter of thread insert top flange (standard size means the middle "00" bore test) root_bore: diameter of thread insert bottom (standard size means the middle "00" bore test) offset_incr_Calc: offset added or subtracted in the series padding: vertical region below the insert for overflow of melted plastic upon insertion length: accommodating length of screw insert_length: length of thread insert flange_height: thickness of insert top flange, usually solid, and not knurled transition_height: diagonal line connecting top and bottom sections of the tapered bore around the insert.
