I posted the other day a thread on using a .040" drill bit and a block of wood as an aid when assembling Micro Trains 1015/1016 couplers ( HERE ). Since I have an Ender 3 Pro 3D printer I designed another version of the 1015/1016 coupler assembly aid using Fusion 360 shown above. It works the same as using the bit inserted in the piece of wood just a little fancier. I'll post the files on my thingiverse.com account ( HERE ). I used the same piece of PCB that I had used before but added some slots in it. The pan head screws locate it on the fixture. I cut it down once I saw that it worked well since the screws take the place of the weights. I found once I had the screws adjusted right I didn't even need to loosen and tighten the right one. As mentioned above you can find the print files on my thingiverse account ( HERE ). You can find all the files to my 3D print files on my thingiverse.com account ( HERE ).
