Glass clip for Wanhao i3 heated bed

thingiverse

Retention clip for holding glass added to the bed of a Prusa i3, also known as a Wanhao i3, allows for printing without support and is retained by an M3.5 10mm nut and bolt. Glass is placed 2mm from an old picture frame cut to size. Take care with placement at the front left of the bed, as being too close to the corner can cause problems. A new longer clip was purchased after cracking 1 to hold 3mm Toughened glass from Amazon, found at http://www.amazon.co.uk/gp/product/B00QM4LUN4?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00. One clip per side holds well with a stick at the bottom of each clip stuck to the back of the bed to navigate around electrical components. 19mm buldog clips on 3mm aluminum beds are now recommended and provide a supply of inexpensive mirror tiles as an alternative solution, allowing for easy glass replacement in seconds with different coatings for various materials for £13. For eight tiles, see http://www.amazon.co.uk/Mirror-Tiles-20-20cm-Qty/dp/B00ABEI688/ref=sr_1_1?s=kitchen&ie=UTF8&qid=1454495465&sr=1-1&keywords=mirror+tiles+20cm. The mirror tiles shown above demonstrate minimal interference with the print head. Instructions: Print at 0.2mm layers without support and with a fill percentage of 20% using no additional instructions necessary.
