Heat set threaded insert test fixtures

thingiverse

I wanted to start experimenting with threaded inserts in my projects, so I designed these test fixtures for testing purposes. I created both straight and tapered versions, the tapered versions featuring a specified taper, while the straight versions maintained the same diameter throughout. The specifications provided by the seller were as follows: 4-40: Overall Length (OAL) 0.135", Diameter 0.159" - 0.153" 8-32: OAL 0.185", Diameter 0.234" - 0.226" M2.5: OAL 3.43MM, Diameter 4.04mm - 3.89mm I purchased my threaded inserts from the seller albersllc on eBay; I'm not aware of the manufacturer's name. Inserts are also available on other websites like Amazon. I built fixtures for the three sizes I bought (4-40, 8-32, and M2.5). The M2.5 and 4-40 measurements were close enough that I used the same fixture. The first fixture I made was for the 8-32 size, with two holes of each size; subsequent fixtures will have only one hole of each size to conserve materials.
