Floater for Senseo Twist coffee maker

thingiverse

This is a replacement floater for Senseo "Twist" (HD7870, HS7871, HD7872, HD7873). It has an 12 x 3.5 mm pocket for an neodimiym magnet. I used a 10 x 5 x 2 mm rectangular magnet to keep the floater' weight minimal and the air chamber volume maximal.There is a rail in the water tank on which the floater rides. An notch and guide make sure the floater will move along the rail without the risk of getting stuck/lodged at the bottom. Print should be paused at 50% to insert the magnet. Select "leave hotend at temp" and "redo layer". Pause should be as short as possible to be sure the floater is water proof. If one waits to long to insert the magnet and continue the print there could be a weak seam mid print.I designed it with 0,8 mm wall thickness all over. This allows printing at 0.2 resolution with 4 walls which should ensure it to be waterproof. 0,2 layer height is also preferable to increase layer density again improving water proofing.I printed it with PETG which is food safe. Also PLA(+) is food safe but can swell & deform when kept in water as it is more porous than PETG.
