21 Apr 19: v2.1 uploaded. I aimed to enhance the design's integrity by eliminating the need for gluing pieces together. This version utilizes a single M4 threaded rod (or long bolt) for both the till roll spindle and two M3 threaded rods guiding the paper around the roll and serving as a tear-off point. Brass rod and domed brass nuts were used to achieve an excellent appearance. The base is thicker, printed with the base on the bed, which aids in getting the sheet magnet to adhere; I also apply UHU Por contact adhesive to the printed part and magnet (far superior to the original self-adhesive surface). PETG was chosen for improved resilience. 25 Mar 18 v1 The original design was liked but a larger version was desired to accommodate an 80mm wide by 80 mm diameter till roll. Given the substantial weight of the 80 x 80 till rolls (335g), and their core diameter of only 12.5 mm, a single-sided arm would not suffice. Therefore, this design features two support arms, with the second support arm secured in place using PVC cement or cyanoacrylate. The design is completed by a removable spindle held by a piece of brass M4 threaded bar and two brass dome nuts. Recesses are included for four Neodymium magnets measuring 12 x 3 mm thick. These magnets can easily support the weight, but they slid off my fridge due to insufficient friction. I believe using Self-Adhesive Magnetic Sheet would solve this issue as it is flexible and provides a secure grip on surfaces. UPDATE: A piece of flexible magnetic sheet was attached to the back, and it no longer slides under its own weight. The overall size of the main piece measures 200 mm long, 90 mm wide, and 60 mm high.
