The plastic sheet enclosure, by MatterHackers, consists of a PVC frame and plastic sheeting. The only trick here is that the PVC must be cut to the right size before the plastic sheet is wrapped around it and held in place with duct tape. According to MatterHackers, this enclosure should cost around $25.
Requirements & Assembly
Naturally, you’ll need some PVC pipes and a roll of plastic sheeting. In addition to that, get yourself some threaded PVC elbows, PVC adapters, duct tape, and Velcro (optional). For the tools, you only require a tape measure and a PVC cutter.
Normally, the process starts with measuring the Ender 3’s dimensions to determine the length of the PVC pipes you to need, but we’ve got you covered: 440 x 410 x 465 mm (17.3 x 16.1 x 18.3 in). Make sure to add a few extra inches to your measurements and record everything on a cut sheet. The sheet should guide your cutting process while making sure you leave minimal waste.
The assembly process will mainly involve friction-fitting the PVC pipes to the adapters and elbows. Of course, you’ll also need to measure the sides of the assembled frame to determine how much plastic sheeting you need. (The plastic sheeting is meant to cover the top, left, right, and back sides.)
The Velcro is meant to be used on whichever side you want the “door” to be one. This a much nicer alternative to removing the entire sheet every time you want to access the build space.
