DIYE Pack of 5 Plexiglass V1 1/8 Acrylic Sheet for IKEA Lack 3D Printer Enclosure | 3 Pcs 440mm x 440mm (17.3 x 17.3 in) & 2 Pcs 220mm x 440mm (8.65 x 17.3 in) | 3mm (Clear Black)

The plexi plates were protected on both sides and shipped carefully. They arrived in perfect condition and fit the enclosure build perfectly. Highly recommended!

Works perfect for my Prusa lack enclosure. Getting the paper off was a chore though

These were delivered well packed with all protective coatings in place. They were easy to peel, and a perfect fit in the holders for the LACK enclosure parts set. Cuts are very good, with only one place that I noticed a little chipping, but quite sufficient for the purpose.

Not cut to the correct size which leaves large gaps. This is a wast of money.

The measurements are exactly as stated down to the millimeter, but be advised if you're purchasing these to complete the Ikea Lack enclosure guide from Prusa that current-generation Lack legs might be slightly smaller than they were when Prusa wrote their guide, resulting in a 3-5mm gap between the plexi and the legs. As another user suggested in their review, I'm going to try filling the holes with weather stripping.

These are transparent plexiglass sheets. Asking me to rate warmth, thickness and sheerness is a bit dumb. It's dimensionally accurate, so the thickness seems to be exactly as advertised. warmth? Really? A function of thickness and thermal conductivity... So on a scale of 1 to 5 stars I would give it a meaningless alligator in a cowboy hat. Also it's reflective and transmissive, so sheerness similar to plexiglass. I hope how I feel about material properties helps you pick the right warmth in your life.

Bought 5 sets of plexiglass from printed solid and they were all off by a couple mm. Bought one set of these and they're exactly at 440mm. Fits like a glove.

Received the plexiglass quickly, cut to the perfect size and easy to install. Might seem a little expensive at first glance, but it is well worth a bit more to save you any headache of cutting the stuff.

Arrived perfect !
