what an idea

@Shanice_1667264 looks like your holes are sealed. over extrusion? i used 0.4mm nozzle and 0.2mm layers. i also printed the fill and inserted it.

for those who are not interested in staying or want to have another option, Thingiverse is getting better. customizer works now but still on the old SCAD version. there isn't a customizer here on this site. the dev team there is (finally) putting a lot of effort in fixing the site. they are also accepting bug reports and feature requests more frequently now. still be patient though. they have a long todo list.
Thingiverse likely has more users than here.
i don't have a way to recieve tips yet aside from btc (crypto). that said, what is your opinion on the idea of keeping the design free but selling pre-made copies using a print farm service (like slant3d) for those without a 3d printer (or maybe they have too small of one)? for the led diffuser, straight versions only and 1m and 2m only. also only 2 widths for the 144/m and 60/m. poll ends in 7 days.
hi. it has been brought to attention that there may have been either a copycat of one of my designs or a site bug. if it is a copy, it is mk404'ed for a while...

...but this may be a bug due to Thingiverse import or the draft section.
need to know when above was published and deleted as well as the user posting to know what happened for sure.

ok. it was another user that had gotten reported.
@spool2kool Just for fun I adopted your 3mf-file for my prusa mk3s and extrudr TPU hard filament and uploaded it as a user print file.Also increased infill to 60%. On the powder-coated spring steel sheet there is no glue needed.
@werz99 "powder-coated spring steel sheet there is no glue needed" that's mainly for pla, asa, and abs. there are some filaments that get stuck too good without a bit of pva on the surface. for example, in my case of the glass bed, pva glue is a must for petg. it sticks so good it can chip the glass. polycarbonate sticks too good to pei.
so if your filament is not listed in below links, a good idea may be to do a small "test" in one far corner. if its good you can do the intended print. if it fails, at least its in a lesser used location in case it chips the coating.
there are these guides (and they do say to use pva for tpu, petg, and pc with it):
