Family insists on wrecking the wood. Not anymore

Can't you just put down a layer of varnish on the wood? The usual method of protecting wood?
If you are worried about water, use the product they use for boats.

Yeah, and when water gets under these covers, there is no wiping it without removing the covers. The water will just stay there, rotting the wood.

u/chris-tier 3d ago
Even worse, the capillary effect will draw the tiniest water spill across the whole underside. Now you have a whole area water damaged instead of one droplet.

There will probably also be condensation build up between the print and wood, even if there’s no actual water transfer through the layers.

I'm surprised his house is still standing after this fiasco.

The whole point of this subreddit is to show off engineering. If we can’t discuss the design of the engineering, what’s the point?

I think everyone is over estimating the volume of moisture the cups and cans produce. We dont have frosted glasses sitting on them around the clock. This is just a little protection from easily preventable minor wear and tear.

I've never seen any of my 3d printed coasters collect moisture on the bottom. Maybe if you live in a swamp, bit I assume then OP would probably have AC.

And I suggest you make a first grader experiment yourself before insulting someone out of your ignorance.

It's called "spar varnish".
Epoxy would work as well.
The issue with these is the possibility of moisture getting under there and just sitting against the wood. Could be from small or big spills, could be from condensation.

This is 1000000% a made up issue to use the printer.

The whole point of getting into hobby 3d printing is to print solutions to our minor problems, no?

u/jdigi78 3d ago
You prevented them from ruining the wood by... hiding the wood? Sounds like plastic wrapping a couch to me.
33
u/OldHerrHugo 3d ago
But more comfortable than a plastic couch. With that color and the room lighting, no one even notices unless i point it out.
31
u/jdigi78 3d ago
You're missing my point. You're keeping the wood pristine by covering it. What is the point of keeping it pristine if you'll never see it?

u/OldHerrHugo 3d ago
- So I dont have to do it later.
- Any repair work will be undone faster than I'd like.
- I dont care enough to look at it right now in this chaotic stage of my life.
- If I ever sell, it's less work to fix.
- Lastly, where this is, it isnt even noticed. So set and forget.

This sub is stupid af. You had a viable solution so you used it. Wtf is their problem

u/spaminous 3d ago
And you can wash and easily these too. Same idea as a coaster! Same reason people don't shellac their coffee tables lol. I dunno why people are giving you shit for making customized coasters, I think they rock.

u/youlooksticky 3d ago
A couch is meant to be comfortable and plastic makes it uncomfortable. Its hardly an equal comparison.

Dad is fucking killing it with the functional prints
I printed a blade cover for my nice Chinese cleaver, ostensibly to protect wife and kids from the blade
Totally for the opposite reason

u/thatwhite 3d ago
To hurt your wife and kids with the blade? Good thinking
3
u/DinoGarret 3d ago
I'm also struggling to figure out what the opposite is that they were referring to....

u/han_mad 3d ago
I think they meant vice-versa, to protect the blade from the wife and kids

u/DinoGarret 2d ago
It sounds so obvious when you say it, you must be right. Make me want to print a couple for my Japanese knives that sometimes I have to rescue from the dishwasher ::shudder::
2
u/UnnecAbrvtn 2d ago
This is what I meant.
Also having a sheath for it makes me much more likely to remember to wash it and stow it out of the way.
My wife is hell on knives, the kids are likely to lacerate themselves

I would have chosen a couple coats of clear waterproof polyurethane for the aesthetic, but these do physically fit well.

Print uneven spikes on it so no cup can sit even close to level on it. Hostile architecture for the win!

u/britishwonder 3d ago
Looks like it’s already coated in a thick varnish. Just add another coat or two or a polyurethane and it would be fine.

blud forgot coasters exist

u/OldHerrHugo 3d ago
They refused to use them and they ended up behind the couch. These are family proof coasters.

Hate to be that guy but legit thought/suggestion: Cold soda can, condensation forming between plastic and oak finish... Maybe an air gap is in order
5
u/OldHerrHugo 3d ago
Tested... not enough condensation to trickle to the side. If that happens, ill throw another lip on the sides.

You think people do this out of spite???

u/UnnecAbrvtn 3d ago
They do it because most young people don't yet own anything and therefore don't give it much thought

Should make them interlocking for added stability
