Thank you for the feedback, I have updated the design to version 2. This has better tolerance and should fit better.
The toolhead on the Bambu Lab A1 mini has a window and the wheel turns during extrusion and retractions. I realise it can be removed and personalized with a window button (I call them window buttons). Initially, I designed a series of these buttons, but due to the size, it will require a 0.2mm nozzle to print finer details. The A1 comes stock with 0.4mm nozzles. and not many will buy a 0.2mm hotend just to print these buttons.
I then noticed that the silicone thumb cover from the Nintendo Switch is the right size, and there are so many different designs available to choose from. In fact, you may have a set of these covers with you at the moment. Hence I designed an adapter button to install these thumb covers to the A1 mini.
To date, my designs are free to download and use. There is no Patreon or OnlyFan (hahaha). If you like my designs and wish to contribute to my coffee addiction & help fund the filaments and materials needed for prototyping, a donation of $5-$10 to Ko-fi or paypal.me will be greatly appreciated.
As with all my designs, Prototyping and testing were conducted to ensure printability and meet my own expectations. However, I understand it may and may not work for you. I would request that you read all instructions and print and install them at your own discretion.
