I just saw 2 fighter jets flying overhead. anyone know what they’re doing?

Hi Everyone,

I'm working on an old tri-hull that developed a soft floor over the winter. I've been doing a lot of reading and watching videos on how to repair it properly, and I thought I had a pretty good understanding of the process.

From what I've learned, the typical approach is:

• Use marine-grade plywood.
• Cut the stringers using a template.
• Coat the stringers with resin and CSM.
• Use putty to create rounded edges where the stringers attach to the hull.
• Cover everything with additional resin and fiberglass mat.
• For the floor, cut it to fit, seal all sides with resin, install it, and then glass over the top.

That all made sense to me until I pulled up the old plywood and saw how the boat was previously repaired. There doesn't appear to be any resin on the floor at all, except where the pieces were joined together, and the stringers only have fiberglass running partway up their sides.

The way the previous owners fixed it looks like a much cheaper and faster approach, but I can't help thinking it's a bit of a hack job that would lead to premature rot. On the other hand, maybe it's considered acceptable for a boat like this.

I'm wondering which method I should use. My gut says to do it properly and be done with it, but if the simpler method is acceptable, it would certainly be easier and cheaper.

For some background, I don't plan on keeping this boat long-term. I bought it at the end of last season mainly for the trailer, but the boat floats and I got the motor running great. Since it's usable, I'll keep it until I get tired of it and then most likely scrap it when I'm done.

Hey Everyone,

I had this printing for 2 days and when I came home, this happened. I thought maybe the print came loose and moved on the build plate, but it was still attached and centered. I'm at a loss and don't really want to try printing it again until I know how to prevent it.

I'm not sure what other info to include. The printer was originally an Elegoo Neptune 2s, but has had many upgrades done in the last couple of years. It has a new board (BTT Octopus v1.1), new stepper drivers, new extruder, hotend, and thermisters. For a slicer, I'm using UltiMaker Cura V 5.9.0 and printing with ASA filament.

Can someone recommend a 2-in-1-out hot end that works well and is compatible with an Ender 3?

The main reason is that I want to use separate material for support and I've tried a few different hotends off of amazon, but they all seem to constantly clog.

Hey Everyone,

I’m fixing up an old boat and the wiring is a mess. I’m planning on rewiring everything with proper fuses and rocker switches and I would like to color code the wires. Other than the standard red and black for the main 12v coming from the battery, is there any color code standards that people use or do I just pick the colors that I want?
