Heavy Duty Spool Holder (For 2kg Spools)
thingiverse
This top mounted spool holder is designed to withstand holding 2kg spools without flexing or shaking while the printer is active. This design heavily draws inspiration from MartinMajewski's Prusa i3 MK2(s) & MK3 Spool Holder - Frame Mount - Top Loader (https://www.thingiverse.com/thing:1832235) as it has a style I liked and has proven itself on my Prusa Mk2.5s printers. This modification uses 2 supporting arms per side, creating a very rigid frame for spools of any size or weight (tested up to 2kg). This style works with all Prusa I3 series printers (up to the Mk3s). ***Parts*** 2x Spool Arm 1 2x Spool Arm 2 4x Bolt 1 4x Bolt 2 2x Clasp 2x Latch 8x Spacer 4x Roller 4x 608 bearings 6x M3 x 10mm screws *** This design does use 6 M3 x 10mm screws and Bearings*** The leftovers from your Prusa I3 Kit can be used for the screws, or you can order some from Fullerkreg (https://www.amazon.com/Fullerkreg-Socket-Stainless-Machine-Quantity/dp/B07CK3RSN3/ref=sr_1_1?crid=173PCAV6SBA8S&keywords=fullerkreg+m3+x+10+hex+drive+socket+cap+screw&qid=1577830633&sprefix=fullerkreg+m3+x+10+he%2Caps%2C299&sr=8-1) This spool holder works with 608 bearings (https://www.amazon.co.uk/ABEC-BEARINGS-skateboard-edge-cruiser/dp/B00HKWS1MA/ref=as_li_ss_tl?ie=UTF8&qid=1476701593&sr=8-2&keywords=608+bearing&th=1&psc=1&linkCode=sl1&tag=thingiverse0a-21&linkId=89179991cad83bffb325d2e2000efa90)
