1/8" Cardboard Sheets 12 x 20 HELP


#1

After five days owning my Pro. I have been cutting a lot of prototype parts for my aircraft. I ran out of old cardboard boxes and would like to find a supplier of sheet goods. Would be nice to get 1/8" and 1/4" 20 x 12 that fits the laser without having to cut the sheet to fit. Once the fit is perfected using Fusion 360 for part design and assembly then I can cut in the correct and more expensive material.

Someone must have a link to a supplier.

I just go to the back of my local grocery store, they usually have a bin just for cardboard.


#3

google paper and packaging suppliers in your area. I just got a bunch of 0.120 chip board for $5 per 30x40 sheet. cheap and very consistent. You might need to order a decent amount but my local place only required a $20 order. I ended up spending $130 on a bunch of other thicknesses and types… but oh well!

they also had cardboard in 40x60 sheets for $5, but that wouldnt fit in my vehicle

Not exactly what you’re looking for, but you can also check neighborhood sites for free moving boxes (craigslist, nextdoor).

Hey, I see an Etsy business opportunity for folks selling stock in exactly 20 x 12 sizes!

Chris… Thanks so much mate. I just ordered a hundred for $70.00 shipped which is acceptable. The parts I make are precision so having new flat stock will really help prototype stuff and make life easier. Funny thing is I was on that website and could not find this size.

Again thank you.

If you’re willing to rip your own, it’s much cheaper in larger sheets.

Dick Blick has free shipping on 28x44" sheets of chipboard with orders over $35, which is a heck of a deal. They have both .05" and .10". The .05" is $1.36 for a 28x44" and the .1" is $3.42 for the 28x44". They also have 22x28" in both calipers.

Tomorrow I have to take my Glowforge to FedEx to ship it back due to a fault, and then this got posted today. Tomorrow only.

I’m still going to see how much I can get. With my luck it’ll turn out to be not laser-safe, but if they’re just going to recycle it anyway I’ll take an armload or ten.

If cutting your own is really not an option, a lot of hardware stores will do it for you for pretty cheap per cut.

I was just playing with the 2.7 mm plywood from home depot today. It cuts pretty easy and cost $10 a sheet. You can have them 40 8 cuts which will net you 16 sheets of material about 12"20" (minus the kerf).
