UPDATE (June 3rd, 2019) I am finding that the switch piece breaks often on the thinnest cylindrical part, so I have made a version two with great success. The jumping of the extruder from print to support makes the part weaker. I designed a new piece that has an insert for a piece of 1.50mm steel wire, which I tempered to on my stovetop to make it harder. (Optional) The switch file has been flipped so less support material is needed, and therefore less jumps.
- Use supports only touching the buildplate.
- Use the same speed and layer height (including start height) for the pieces
- Clean up the print thoroughly
- Squirt glue down the insert hole as well as some on the top (I used clear gorilla glue)
- Twist while inserting wire with pliers
- Wipe off excess and let dry
- Install safety as before with V1
- Reinstall in marker before use! (Otherwise the ring will just twist out of place, make sure it's right-side-up before pushing into the frame of your marker.)
This is a conversion for Empire BT (Battle Tested) Paintball markers to remove the original push-button safety and replace it with a flipping lever safety. The reason for this new safety is to reduce the chance of accidentally turning the safety off when setting down your marker, and vice versa when in battle.
These pieces need to be neat and exact, so I printed my pieces at 20mm a second. Since the main piece doesn't have that much surface contact on the bed while printing, I recommend using a glue stick on the bed. Supports are obviously required on the first piece. Some sanding may be required.
How to Install:
Steps shown in photos!
1. Take off the pistol grip from your BT marker.
2. Pull out the old push safety from the left side.
3. Take out the trigger Mechanism.
4. On the same side you took it out from, place the 180 degree stop piece (2nd Piece) on top of the hole from the inside. (The cut-off corner facing forward)
5. While holding the stop piece in place, slide just the end of (1st) Main Piece in so it is flush with the stop piece's top. Note that the lever (1st Piece) must stay on the top 180 degrees otherwise it will not go through. (Because that's what the piece is meant to do.)
6. Wiggle the trigger mechanism back into place.
7. Slide the lever (1st Piece) the rest of the way though the trigger mechanism. (You may need to file/sand a tiny slot for the bump on the switch to fit through.)
8. Reassemble your marker.
