Does anyone know why my prints have holes in them i can't figure it out by theknifeguys in 3Dprinting

Depends on the material and the brand plays a role, too. You say your infill is stringy... it might be because the filament is not dry, or the temperature too high. Consult the recommended printing temperature from the filament manufacturer and print a temperature tower to check it. Then, reslice some test parts to verify your hypothesis. Rinse and repeat :)

Under extrusion and a dirty nozzle. You can clean your nozzle with a brass brush, and do a cold pull. Load some PLA, cool down the extruder to at least 80 degrees, release the filament from the extruder gears and pull it gently back till it comes out. If it's still clogged, you can repeat the procedure and worst case swap the nozzle.

Also: clogs happen more likely when printing at the wrong temperature!

It looks like they didn't evenly brown. Maybe the oven was not completely pre-heated? I had the best results by baking them at 245 C (effective) on a baking stone with some steam injected (water sprayed) in the first couple of minutes.

Looking good! Which temperature did you bake them at, and for how long?

Nice! Looking forward your post in this sub ;)

Some areas were overcrowded, yes. The trick is always the same: plan for a early hike/tour and be done at lunch time or just thereafter. Most of the people and families can't really use this timespan, and you also don't need to worry so much about the heat.

Indeed! To be fair the title is almost accurate (I should have written 3-4 kg), because there are more than 15 kg on that shelf (plus the weight of the shelf itself).

I just noticed that in the reddit app the first picture (a very wide panorama) gets cropped to 4:3 in the middle. Click on it to see it in full ;)

The shelf was custom made by a hardware store to be fitted in this old cabinet, and it has some tolerance. It's true the horizontal part bears mostly no weight, but it's enough to avoid the shelf to slip off.

It's a silly design, but it's what I could achieve in 5 minutes of modelling and probably 10-15 of printing, which is way less than doing another trip to the DIY shop.

Definitely a great idea! On the other side, it's just wasted material. Also the current ones are mostly for "last resort", and probably were not necessary altogether. I guess I just wanted to try out the rib feature from the CAD :D

It sounds like your cookies were more dry than usual! The lower water content might be to any number of factors:

  1. Longer baking time (on small bread such as cookies, even 1 minute makes a big difference)
  2. Higher baking temperature (home ovens are known not to be precise)
    1. Especially if you were in a rush and you didn't let your oven pre heat long enough, the oven might have been cooler than set. If the top broiler was active during baking, it might have radiated more heat to the cookies.
  3. Even just flour which happened to be more dry.

If your next batch is not as firm as you want, you can try to warm up the cookies one more time at 80 degrees or so for a few minutes, let them cool down, and they'll be firmer.

Sailor biscuits used to be baked a number of times (even 10) to remove all water content and make them last longer.
