<p>This is my modification of the top shell of the ploopy thumb trackball (<a href="https://github.com/ploopyco/thumb-trackball">https://github.com/ploopyco/thumb-trackball</a>) to convert it to use bearing-transfer-units.&nbsp;</p><p>Originally discussed at <a href="https://www.reddit.com/r/ploopy/comments/r3cgjc/first_draft_of_a_btu_mod_for_the_ploopy_thumb/">https://www.reddit.com/r/ploopy/comments/r3cgjc/first_draft_of_a_btu_mod_for_the_ploopy_thumb/</a></p><p>BTUs from here: <a href="https://www.aliexpress.com/item/32827937931.html?algo_exp_id=8d5a444b-42c5-4b12-9659-3a2b2539ae70-1&amp;pdp_ext_f=%7B%22sku_id%22%3A%2265079016612%22%7D">https://www.aliexpress.com/item/32827937931.html?algo_exp_id=8d5a444b-42c5-4b12-9659-3a2b2539ae70-1&amp;pdp_ext_f=%7B%22sku_id%22%3A%2265079016612%22%7D</a></p><p>&nbsp;</p><p>Note that the ploopy files are originally licensed under CERN-OHL-S which prusaprinters does not support; I have chosen what &nbsp;I believe to be an appropriate license.
