Belt holder, mag tool hook

belt loop i made for my brother in law to hook his concrete tool on  when finishing concrete. found it works better when using tree support. i printed it on its side. i drew in autodesk, if anybody would like help with changes let me know! i recommend doing like 4 or 5 walls, for rigidity/ and or making the hook part solid. however after a few prints i think it would be find with infill.

i added a text that cuts into the part you can customize or delete.

my first uploaded design,so please let me know any tips or tricks on what to do/ not do!
