My 3d printer has an enclosure, from Unitak.

It helps in a number of ways:

• Keeping dust off the printer
• Preventing drafts that can affect print quality
• Stopping the cat from trying to eat the filament purges or interfering with prints

However, the cat has been jumping onto the enclosure, which has snapped the corners of the frame holding it. I was unimpressed with the frame - fibreglass rods (itchy fingers!) and plastic corner pieces that don’t hold up well under stress.

It has clearly seen better days. It’s holding up just enough to print.

My idea is to buy aluminium extrusions, and corner parts, and use that to reconstruct a more solid internal frame, since the cover seems quite rugged.

Today I found ooznest.co.uk, a vendor that sells pre-cut aluminium extrusion lengths.

The plan is to order these precut lengths, based on inner mesurements, leaving space for the corner connectors on each end. I will also order some corner connectors that fit the extrusion profile, and use them to assemble a new frame inside the existing enclosure.

It might be tricky to assemble some of the rear corners, given the way the enclosure opens, but I think it should be possible.
