This is a mold for casting the Benchy

The Benchy shape had to be modified to be demoldable. My Intend was to cast a candle as you see in the pictures.

Printing

• print the two halves with the following orientation:

• I successfull printed/casted with generic PETG 0.2mm layer height on an A1

• the seam line between the two halfes mated perfectly

Casting Wax

1.  thread the wick through the two holes.

2. tie a knot at the chimney part of the mold

3. consider using a mold release "agent" like (kitchen) oil.  Especially on the upper part of the benchy.

4. Close the two halves

5. Use a Clamp (or tape) to keep the halves shut and fixate the wick on the other side of the mold

6. liquify the wax (can be done in a water bath)

7. pour the wax in the molds

8. slightly tilt and tap the molds to release bubles

9. when wax retracts in the mold, repour some more wax

10. Cool down (for example in a freezer for 1h)

11. undo the knot

12. gently tear the molds apart. 

13. pull at the bottom wick to demold the upper part. 

14. if demolding is difficult:

    1. Prop somthing between the molds (like m4 nuts between the two molds where the alignment pins are) and secure the two molds togetherwith some sticky tape

    2. use the provided push pin and gently push through the upper wick hole

15. cut the wick at the bottom.

Casting other stuff

• Consider using an apropriate mold release agent

• The mold has draft angles of 3°

• Scale the mold according to your need

Notes

• Just melt a candle for the wax and the wick!

• Some wicks have a "Direction", so keep track of the top while threading it in

• my first one demolded graceously without breaking. for the next two i was not as  patient and the thin parts of the bow broke. This is fixable, just hold the pieces in place and come close with something hot and remelt the parts together!

Have fun!
