I designed a custom motorcycle mirror mount to be 3D printed in AlSi10Mg. I aked google to determine the pilot hole size for an M10 tap and it give me 8.5mm size, could someone please verify if this sizing is correct size before I print?

The goal is a 10mm thread. Does anyone have the correct drill/pilot hole size recommendation for an M10 tap in this material?

Thanks!

Context: Handle bar clamp with side mirror mount 10mm

Edit: I apologize forgetting to include the thread pitch. its 1.25

Hey everyone, I need some feedback on a custom brake master cylinder clamp I designed for my bike.

Just to be clear: * This specific clamp angle doesn't exist on the market, so buying a commercial one isn't an option since only available is straight angled clamp.

• CNC metal machining is way too expensive for a one-off, so I am sending this file to a professional 3D printing service to get it made.

The part has to safely handle:

• Non-stop vibration: It's right on the handlebars, so it can't be made of brittle plastic that cracks over time.
• Heavy clamping force: It needs to bolt down tight onto the handlebar without stretching out or loosening up later.
• Hard braking: I have really decent grip + 17mm brake master. When I pull brake lever it multiplies at some rate and it will puts a lot of pulling force on the clamp.
• Weather: I want a rain, sun, and humidity.

Right now, I'm planning to ask the printing company to use Carbon Fiber Nylon but let me know if there are better/best material for my use case that you strongly suggest.

Please check out my design geometry: If you see any weak spots or areas where the plastic might snap under stress, let me know how I should change the shape to reinforce it.

Is this project impossible or possible, if possible what material do you strongly suggest?

Thanks!

Good day mga sir, may nakapag DIY naba dito CNC na part ng motor? May personal part kasi ako I made it myself in CAD specifically sa clearance ng motor ko. Kaso most ng napagtanungan ko na CNC Service sa fb ayaw nila tumanggap ng small/hobby projects. Baka may kilala kayo na tumatanggap CNC ng small projects. Thanks & ride safe po.
