In 4 minutes you will learn how to modify a copy of the existing drawing to print only a narrower part of the top 8cm

Steps:
-Save the file under a temporary name.
-Push down the outer shell to get it out of the way.
-Edit the sketch and draw a 6x8cm box at the top, offset it twice outwards 0.8mm each.
-Draw another line across the bottom of the box 5mm up. Save the sketch.
-Go home, make the sketch visible.
-Select the inner shell and extrude it upwards 2cm (edit the extrude and set the operation at 'Join').
-Select the outer shell, set the operation at but and extrude it up and down (verify there is air space all around it).
-Using the 'Cut' operation to extrude the 5cm section upwards, fillet its bottom edges.
-Select it and 3D print it.

Beer Bottle Master Mold via 3D Printing
A project that took several years of failures and blind allies and is finally coming together - so much simpler than expected! |
---|
In Fusion 360 I sliced off the top of the bottle and formed a small box around it to be able to quickly 3D print a test case mold of just the upper neck. Two of these printed in about 3 hours, I cast plaster mold halves from them. Making a hole in the middle of the wire mounts was easy at the leather hard stage. The wire is 2.8mm dia, a 9/64 drill bit is 3.5mm. Simply twisting it to create a hole in the center of the pads takes seconds. Firing these to cone 6 enabled testing the fit for the swing assembly. I followed this with two more iterations to perfect the pad size and hole diameter (ended up at 11/64").
The link below links to a step-by-step in Fusion 360 of how to save a temporary copy of the mold drawing and modify it to isolate just the top portion of the neck.
