Casting Flask Lugs - Pin Design

All credit to Olfoundryman over on YouTube for the idea. If you have not seen his videos, then they are worth a look if you want to see some very valuable trips on metal casting.

This is my "Version 2" of the Lugs/Ears for metal casting flasks and include:
- Pattern for the Lugs themselves
- Jig to help drilling the holes square
- Feeder in case you need them to prevent shrinkage
- For those with a large enough resin printer, a Pattern Boad with runners and lugs

This idea of the design is:
- Easy to print and Easy to cast.
- Smaller profile so it can be attached to frames down to 40mm heigh.
- Uses 8mm partially threaded bolts (cut the heads off and bolt onto the top Lug/Ear). Pick a bolt length to suit your flask.
- Can be attached to wood or metal frames.

Printing: Nothing special but FWIW:
- I printed the patterns of a Resin Printer as it gives a castable pattern without any sanding
- I printed the Jib on an FDM printer as it is cheaper
