This is designed to straddle a bath and hold various soaps, shampoos, dispensers, loofahs… what ever you might need to store.

The overall legth is 750mm (29.5").

Each part is designed to fit on a 256mm bed (i.e. a Bambu P1S/P1P/X1C).

Printing:

The 3 large pieces (end L, mid, end R) print flat on the bed with no supports.  You need 1 of each.

The feet should be printed in TPU or similar so it grips the bath.  I'd say 4 at each end is the minimum needed.  There are holes along the length if you want extra support or to stop the bath bridge sliding.

Pins & Joiners:

These are designed to print with the largest flat side down so layer lines run opposite top the big parts.  Glue them into the appropriate hole.  Do a dry fit first and sand down slightly if it's too tight.

You'll need 4x pin big for joining the pieces.

Extra pin big & pin small can be printed to reinforce the layer lines if desired.  I'd recommend this for PLA and similar, but with ABS/ASA/PETG/etc, these parts are probably not needed.

ABS:

I decided to print in ABS.  With parts this big, that's a challenge!

Use a decent brim, maybe some glue/sludge.  Another tip for ABS I saw was to place small magnets on the brim when your print gets high enough - I'll be trying this in a few days.

I ran out of filament as the centre part warped on me.  Once the new filament arrives, I'll try again.  In saying that, the end R piece came out perfect.  All the pieces printed are insanely strong.

I'll update this listing when I try again.
