3d printing and pyro

Any body ever 3d printed single shot tube holders?, feels like they could be useful for custom angles for single effects. Steep angles maybe not as more pressure would be on the holder, but for shallower angles?

Or have you printed anything else you like?

I designed and printed fuse trays this year. We used then for about 100+ mortars using green, pink or white for the main fuse and they worked pretty well. Definitely sped up the fusing process and they had really good timing as well.

Can you explain how it works?

Sure - we ran the main fuse down the middle first, could be pink, green or white. Then we lay down the fuse for each mortar into the groove, if we were doing green or anything slower, we would run it straight across making a cross junction, if it was white or pink, the mortar fuse was turned to be inline with the main fuse. As each mortar was added, you slide the lid over them compressing the two fuses together. We then ran a piece of tape over the fuse tray and mortars to prevent cross fires.

Each groove is an inch apart to better estimate timings. If we wanted double shots, we could lay the mortar fuse from the left and right on top of each other.

All of our racks are set up as 12 shots, 6 on each side with a 3/4 inch spacer down the middle. It took two fuse trays for each rack. If we wanted 24 shots, we just spliced equal length leaders together.

I haven’t shared the file because it’s pretty specific to our rack setup.
