Original Prusa Top Edge Plug with couple for PC4-01 (Rc1/8)

Replaces the top edge plug of the original prusa enclosure to pass through a filament.

Useful if you're using a drybox!

This was inspired by sajay's design, but I didn't want to use a coupler on the top.

This makes changing filament much easier - you don't need to push the coupler to pull out the  PTFE tube, yet it is reasonably secured with a snug fit.

How to use

Preparations

• 1x PTFE tube, ideally coming out from a drybox
• 1x PC4-01 (4 mm, Rc1/8) coupler
• (optional) 1x 3 mm drill
• (optional) 1x 4 mm drill

Assembly

1. (optional) Use the 4 mm drill to clear the PTFE tube hole, and the 3 mm drill for the rivet hole - you shouldn't need power tools, twist the drill bits with your hand
2. Disassemble the default spool holder and PTFE tube holder - keep the PTFE tube
3. Screw the coupler into the printed plug as shown in the photo
4. Pop the default plug (push the other side of the rivet with the back of your nails) - keep the rivet
5. Insert the printed plug and secure with the removed rivet
6. Plug the disconnected PTFE tube, it should be like (FS-cover – PTFE tube – printed plug)

Using

1. Pull the filament out from the PTFE tube from your drybox, and push it into the cover's hole
2. When the printer is ready, push the filament in
3. Once the gears are pulling the filament, push the PTFE tube into the hole - it should fit nicely
4. When unloading, simply pull the PTFE tube, and you'll have access to the filament (no more fiddling with the coupler!)
