Litelok X3 clasp BMW Vario top case

I have a Litelok X3 for my motorcycle.  When riding, I put it in my BMW vario top box but it rattles around and smashes about whenever I go over speed humps.  So I wanted something that would let me strap it in place in the top box.  I looked about and there wasn't anything ideal I could find that was low profile and simple.  

It comprises two parts: a TPU strap ("flex strap" by @Voyajer) and a base to support the Litelok X3 padlock through which the strap is threaded.  The size of the base was chosen so it would just about fit a 3M GoPro sticky pad - I had to trim it down a little; if you want you could adjust the .stl to make it slightly wider to avoid the need for that.  I thought about recessing the sticker into the base but the added height was useful.  I've printed out three as the Litelok is a good 2kg and I wanted to spread the load.

I printed Voyajer's strap in TPU at 50% so it's sturdy.  I had Overture TPU and it came out fine.  It's the perfect length too - you could shorten it by 1 or 2 cm but that would give you less of a grip when lashing it.

The base was printed with prusament PETG and 30% infill.  The gap for the strap to go through is 2mm.  Voyajer's strap is only 1.5cm across but I think it'll do the job without being widened; time will tell!
