3D Printing Ejection Charge Cannisters

Ejection Charge Canisters


Used on many of my rockets. Currently 1g, 2g, 3g, 4g, 6g, 8g, and 12 g tubes. Sizes are calibrated assuming 1g of FFFFg = approximately 1 cc. The bottom takes a #4 or M3 screw to hold it to the bulk plate. The hole at 45 degrees is for the wire to exit.

Printed with 40% infill for strength. So far these have withstood up to 8 uses. Will add any sizes you request.

You are using black powder - use at your own risk.

I think I'll test with Inland ABS-Like Resin.

ABS is a good choice. I like Inland ABS. I have found it for about $20. Well worth the price. Polymaker ABS is another good choice.
