Spoolholder for 2020 aluminium profile

So this is a filament spool holder made for attaching to a 2020 aluminium profile.

I made it with some of the design elements that Tech2C used in his part. Works fine with a 1kg spool.

would love any input, this is only my second part ive put up here on thingiverse, so i might have done some silly mistakes :D
