After washing the caravan curtains we noticed that some of the curtain stoppers were missing. Now off course we could go out and and spend a few euro's on a bag of new ones, but where's the fun in that? :)
I found a few models but most were made for “normal” curtain rails instead of the T-shaped ones we have in our caravan. Or they used normal M3 bolts.
Ended up remixing HAMMER_T's “Curtain rail stopper” since it had a nice flat end wich I could easily modify for T-rails. Also it included f3d files. (Not proud of what I did to those, so only posting the 3mf files myself).
Due to the modification of the female part I had to print it standing upright. This did not affect the shape of the hole enough to make the bolt not fit.
After a first test I found that the “bolt” was too long for my application, so in the M+F file I added a negative volume to shorten it 3mm.
The “in use” photo also shows one of the old stoppers that was still there.
The author remixed this model.
