3D Printer Enclosure Ceiling Spool Mount System

3D printer generates harmful fumes, so I decided to put my printers in enclosures.

I used Ender 5 enclosure for my Makergear M3 and Ender 3 enclosure for my Ender 3. Since those enclosures are tall, I decided to hang spools on the top of the enclosures to have more side space.

I used a 1/2" schedule 40 PVC pipe to hold the racks which is pretty cheap at Homedepot or Lowe's.

To hold racks, M4-0.7 x 40 mm bolts and M4-0.7 nuts are used.

Used following spool holder, but not limited to the linked spool holder.

I made side and rear versions. Recommend rear version with spacer which will prevent spool rack bending by heavy spool weights.

Use at your own risk please!
