2Laser Cutting
Insert acrylic sheet. Fit the sheet to upper left. Move the file to Laser Cutter and set Laser preferences. Cut the acrylic sheet with the laser cutter. Take out the acrylic sheets. Cut another thickness of acrylic sheet.
3Prepare Bonding
Here are acrylic sheets cut with Laser Cutter. We will make 2 sets of molds. (Set 1 : A+C+E+F, Set 2 : B+D)
4Acrylic Glue
Transfer some acrylic glue to the applicator bottle.
5Set 1 (part E + C)
Put part E and part C. Align the position of acrylic part.
6Glue
Fit the together tight. Use the needle to put the glue into the gap between the acrylic sheets. Hold it tightly for a few seconds. Add more glue if it looks not enough.
7Set 1 (part E + C + A)
Put part C and E on part A. Align the position of acrylic part. Put the glue into the gap.
8Set 1 (part E + C + A + F)
Add an inner part F to allow air flow. Put part F on part E+C+A.
9Set 2 (part D + B)
Put part D on part B.
