YALGWPI (yet another linear guide with ptfe inserts)

I printed a linear guide with PTFE inserts. Like others of you already did. I liked your works and made my one for 30x30 mm profiles.

After adding some ptfe spray, it slowly slides down the profil by its own wight. And i don't feel any cleareance
