Original Prusa i3 MK3 3030 T-Slot Extrusion Channel Cover Set

Good model!

Good model but very tight, I had to trim one of the rails on all of them to get them to fit. They probably would have done fine if I installed them during assembly.

Fit´s great , thank you for the Design

I use it on my MK3-s and all so parts on my Mini-s

Nice concept but hard to install, had to shave plastic to fit.

If you like me had trouble getting the covers into their slots after already having assembled your printer, check out my remix that I created to solve that problem exactly!

Alternatively, if you've already printed this model and don't want to reprint, I found it is still possible (though difficult) to snap in these original pieces by clipping the ends and trimming off the final layer. I also had success with this model by specifying a Height Range Modifier starting at 3.5mm until 4mm and telling the printer not to print the final 2 layers. But if you're going through that much trouble you might as well just print the remix.

Happy printing! (edited)

I like the concept behind the idea.... I just wish these were easier to install on an assembled printer. Kinda gave up installing them for now... tried to pry in with screwdriver but that just damages the pieces. As others have mention, this is more appropriate to insert during assembly of the printer.

The print worked fine with PETG and it's a nice slick design. Sadly, a little to slick. I've failed to install them...

Printed nice but they're hard to install.

The ones under the rods are a bit tricky but they will fit. What I did was install them, then with a bit of round steel rod, I ran that up and down the inset to make it absolutely flush with the surface. This clears the u-bolts for the heatbed. I've been running them on my printers for about 8 months now and no issues at all.
