the next thing you want to do is get a self adhesive sheet of PEI. 220x220 should fit nicely - after you cut it to size :-)
About $10

Once you've got that - you won't need any glue or hairspray or tape. And I tried EVERYTHING on my original creator.
printbite is what fixed everything :-)
But cheap pei is almost as good.

Don't run it any faster than 70mm/s
Also print one of these: https://www.thingiverse.com/thing:537918
YOu'll need a 24v 40mm fan and a couple 3mm nuts and bolts.

And that's pretty much ALL the mods a replicator ever needs.
I also made my spool holders a lot smaller diameter - but that was because I had a few apols of odd stuff with 12mm holes. So used an adaptor and a couple 10mm bolts to replace the big plastic cylinders.

One of the most reliable 3d printers on the planet :-)
