Backrest raiser for Thule Urban Glide 2 stroller

The most upright backrest position on the Thule Urban Glide 2 stroller is too reclined. This gadget props it up higher. 

It's based on the ingenious design by @Thomas_157995 which is really clever and well done. 

I've used one of Thomas's brackets for some time and it worked nicely. However, it only holds the backrest in one spot and when there's significant movement (the kid throwing a fit, or the stroller going over bumps), the bracket can shift and fall out.

So I printed a second bracket and used both of them at once. More stable but still prone to falling out when the child starts going nuts in the seat.

This design simply connects two of these brackets with pretty heavy-duty crossbars. Nothing magical, but it works quite well. There's also a small hook on the very back of the bracket so it's less prone to move forward when the kid pulls the backrest forward.

So far, so good –  rated 5 out of 5 by children (n=1) and parents (n=2)

Printing

This comes out at about 3x the amount of filament used in Thomas's design. Mine came out to a respectable 130g. Robust and worth every penny though!

How I printed it:

• Anycubic Kobra 2, Klipper, PrusaSlicer
• JAYO PLA+
• Nozzle 0.4, layer 0.25
• Organic supports
• Perimeters: 4, top/bottom solid layers: 4
• Infill: 5% gyroid
• Orientation: crossbars must be vertical / printed upright. See slicer picture.
• Cost: 
  • weight 130g
  • approximately CAD $3

I printed it at a high speed (~250 mm/s) with Klipper and that's probably why the bridging over the top of the supports was quite bad and I've had to clean up that face extensively. 250 mm/s is at the very top of the advertised range for my printer.

It didn't affect the strength of the part but you'd be smart to print more slowly. Maybe higher support branching close to the part would give better result. Please share your wisdom, I'd appreciate the advice!
