Lezyne Tech Drive HV/HV Drive MTB Hand Pump Bolt-on Frame Mount

Print vertically(tall way) standing on end so it doesn't break on layer lines when the pump is clipped on. Print in PETG 100% infill. The pictured print was using fuzzy skin for the texture. ABS GF, PETG CF also work great and give it a nice matte look. PLA can crack for this use case but you're welcome to try it.

I've been using this model for a year now and it holds the pump firmly, but I'd still recommend using a velcro strap like the one that comes with the pump. This model has a slot for the original strap.

Let me know what you like. I'm happy to make changes if you have any suggestions. I'd love to see different colors that match your bike. Let me see your makes!
