Dog Showerhead wall mount - 3M compatible

I give my dog a shower in our bathroom shower stall. I use a showerhead that gives on/off control in my hand. I thought it would be handy to be able to hang this showerhead on the shower stall wall while I was massaging shampoo into the dog's hair, etc. This mount can use the large size 3M Command adhesive strips. It uses 2 of the ones they market as water resistant. When the directions are followed carefully, I've found these strips to hold up very well. I.e. carefully clean with iso alcohol, apply as indicated, apply and hold pressure for about a minute. I found that if this adapter is printed the way it shows up in Bambu studio, i.e. with a 0.4mm nozzle, with the objects on their sides, the surfaces the adhesive has to stick to are smooth enough for the adhesive to work. I printed the final version with ABS in a P1S printer. I did successful test prints using PLA. I'm using a brim with the particular brand of ABS I'm using up at the moment as one print failed due to
